Q: I am looking to buy a dvd player for my parents and they purchase d a wide screen tv so when you play dvds or watch tv it tends to stretch out the picture. Is there a dvd player that takes this into account or does it matter?

 

A: There is a common misperception that the screen should be full. Not so. While it is nice when it happens only material at the same aspect aratio (width to height ratio) as the screen you are watching will fill the screen ... everything else will have black bars on the top and bottom or the sides (unless the image is stretched or zoomed ... but that distorts or throws away some of the picture).

 

The director of a film chooses the aspect ratio, and it can vary from 1.33:1 to over 2.7:1 in extreme wideangle films. The most common are 1.78:1 (so called "16:9" -- the aspect ratio of "widescreen" TVs), 1.85:1 and 2.35:1, but others exist too.

 

See the image at the link to see how these aspect ratios relate on a constant width screen.

 

TVs often have a control that allows images to be zoomed or stretched to fit the screen ... as stated above this is distortion and most people, after playing with the different settings for a while, return to a straight undistorted image setting.

 

A widescreen TV will "fit" more programming (particularly if they subscribe to HD programming, which is in widescreen (16:9) format) than their old style TV (Which was 4:3 or 1.33:1 format) BUT they will still see black bars on some movies, particularly on DVD (Note: TV broadcast stations sometimes crop widescreen movies to "fit" the 16:9 screen ... and you can't control this, but the same movie on DVD might have bars).

 

So ... no, you don't need to buy a different DVD player for widescreen since the basic aspect ratio is determined by the movie, not the player. Maybe the above explanation will help you explain it to your parents.

 

If buying a DVD player for a 720p or 1080p HDTV, consider a $100-$125 (less expensive ones won't provide any benefit) "upscaling DVD player" (with a HDMI connector) or if you want to go full out, consider the Venture HD DVD player from Walmart ($200) ... which is really a Toshiba HD-A3 player (a good upscaler and it plays HD DVDs).

Q: I'm trying to get DVD audio into a mixing board(radio board) cleanly. The DVD audio is clean UNTIL I connect it the video cable between the TV and DVD player, then a strong hum comes through. I tried different tvs and dvd players, and the hum always returns once the video connection is made between the tv and dvd player. I've also experimented with grounded power strips and shielded cables with no success. I'm trying to get DVD audio for audio production, so the hum negates using the 'hum-backed' audio.

 

A: The problem you are experiencing can be really really difficult to solve. I have spent hours and hours chasing hums in distributed AV systems. The quick answer is that there is a ground loop issue. This site has a couple of ideas

http://www.channld.com/hum.html

You can often get rid of by plugging all of the components into the same outlet, which remove ground difference since they share the same ground. Cutting the grounding pin off of your component is not usually a good idea, as it leaves your component ungrounded. If you have cable (as in TV signal) running into any of the components, there is often enough DC current in the cable signal to cause a ground hum. You can buy a cable ground lift from Radio Shack. I hope this helps...

Q: Everything you know please say....im clueless on this one...I am getting a video camera for my fiance cause we just had a new arrival to the family :-). Which one is easiest just to get on a dvd to put it in the dvd player and watch. Do you have to transfer stuff from mini dvd to an actual dvd once its recorded?

 

A: MiniDVD (Mini DVD or miniDVD) is an 80 mm diameter DVD  disc. In normal recording (standard DVD quality), it holds 30 minutes of video or 1.4 GB of data. Under SLP mode, comparable to VHS quality, it can hold 120 minutes of video. It's commonly used in camcorders, but the 80mm size was originally used for music CD singles. It can be played back in most DVD players that are tray loaded. The trays on players and DVD drives have an inner ring where the 80mm disc in centered for loading in the player. Slot loading players cannot use this format.

 

The format is also known as a video-single, or DVD single, being analogous to the CD single (miniCD) in being a singles format for music videos.

 

MiniDVDs (80 mm) are known also as "3 inch DVDs," referring to their approximate diameter in inches.

 

Mini DVD-R/-RW media are available and are marketed for use in some newer, DVD-based camcorders that record directly to the 80 mm DVD disc. Typically, these cameras offer three quality settings in varying bitrates: XP (20 minutes), SP (30 minutes), and LP (60 minutes).

 

Single Sided Dual Layer DVD+R and DVD-R forms of this media are now available. Released in Q2 of 2006[1] they boast 2.66 GB of data storage and hold up to 55 mins of continuous, Standard Definition video with recording speeds on a par with DVD-9 DL discs.

 

Although working out at around 1 (US$2) per gigabyte, they are aimed at the Camcorder market where they will nearly double the length of recording time but are also compatible with DVD players and drives that support dual layer media.

Q: I want to <a href="http://www.video-to-flash.com/video_to_flash/"> copy dvd movie's onto usb flash drive's </a> to watch on

my eee pc for oversea's travel. I have divx and quicktime player installed but none of them seem to want to rip the dvd to the usb.

 

A: This is possible but it depends how you want to copy it. Do you want it in avi format or dvd format.

 

If you do leave it in dvd format it will be 4.7gb per movie

 

but

 

If you shrink it down then you will be able to get it to around 700mb.

 

To make it an avi:

 

# For converse conversion like our subject indicated: Editing Rip a DVD to an AVI or MPG File Using DVDx

# Download DVDx archive file to your computer (DVDx_2_10_setup.zip), open it and double-click on "DVDx Setup". Complete the installation of DVDx.

 

*

o Ensure you have XviD (and/or DivX) drivers by installing AutoGK or downloading codecs separately.

 

+ Download the latest XviD free from xvid.org.

+ Download the latest DivX free from divx.com.

 

# Now run the DVDx software. The program window will appear.

 

You should insert the DVD you wish to rip into the DVD drive. Alternatively, if your DVD is saved as files on your computer, you can rip from there.

 

On the DVDx window, there are three menus available, File, Settings, and Tools.

A file window opens, and you can browse to your DVD.

 

Alternatively, to open DVD files which have been previously saved to your hard drive, click "Open IFO" to select your hard disk files as source.

 

In the folder selection box, select the file VTS_01_0.IFO in the DVD target directory on the hard drive.

 

Your movie is now loaded as source.

 

The Input Settings dialog automatically opens.

 

# Notice that the Input Settings dialog will show, in the Program Chain Index section at top left, the length of the movie to be processed. Check a suitable audio track is shown in the Audio section.

 

* Other settings can be left at default.

* Note: If during conversion you get an error "DVD drive could not be locked", you should install ASPI drivers (from Adaptec), and then select the "Use ASPI" option. Otherwise this will not be necessary.

* Now click OK.

 

# Navigate to the Output Settings dialog box (shown below) through the Settings menu. Here you can choose output options such as movie format (AVI or MPG), and set the screen size (resolution) and audio quality.

 

# Change several settings in the Output Settings dialog box:

 

* Choose an output format (AVI is suitable for playback in Media Player).

* Now choose an audio compression method. Lame MP3 is capable of excellent sound at small filesize (AVI only). If Lame is not available, choose the MPEG video compression, or download Lame MP3 drivers.

* Choose the XviD video codec in the dropdown menu. Click 'Enable Video', but leave 'Enable 2nd' unchecked. You can choose an alternative video codec (such as DivX or Mpeg4) if you prefer.

* Across in section Export Settings, choose a screen size (resolution) for encoding.

 

o For widescreen monitors (size ratio 16:9) choose 720x576. Any multiple of 16 is acceptable.

o For normal monitors choose (size ratio 4:3) choose 720x544. Any multiple of 16 is acceptable.

 

* Next to the Max Frame number, click the button named Whole.

* Other settings can be left at default.

* Click the Apply button.

 

# Finally, under the File menu, click the menu item called Destination.This button is also found next to the red Record button at the bottom right.

 

* Browse to a suitable destination folder, and type a filename into the box. Click on Save, then OK.

* You are now ready to convert a DVD to an AVI.

 

# Click the red Record button at bottom right.

# Wait for encoding to complete and then enjoy your movie.
