My dvd player has only coaxial, s-video and av cable connectors. The laptop I'm buying has â¢3 x USB 2.0 ports, 1 x HDMI port, 1 x VGA port, 1 x RJ-45 Ethernet port.
Do I need to buy a newer dvd player? My tv is ancient having only a coaxial connector, so if I can connect to this dvd player it would be best.
Thanks for your help.



Answer
Laptops do not normally have A/V inputs the way TVs and monitors have (the HDMI and VGA on the laptop are for video output, not input), so if you were planning to watch DVDs from the DVD player on the laptop screen, that won't work.

Anyway, if the laptop has an optical drive that's DVD compatible, you can just put the DVDs in there and watch them, without needing any separate DVD player.

The only other thing you could try, but it won't work very well, is to get a USB video capture device, like this one: http://www.amazon.com/Diamond-VC500-Touch-Capture-Device/dp/B000VM60I8/ref=sr_1_1?s=electronics&ie=UTF8&qid=1301800999&sr=1-1

(But those are designed more for capturing/recording video to play back later, rather than watching it as it plays - so the video may be jerky, the sound may not be audible until you play it back later, etc.)

What type of dvd player would work best for a tv that is already a widescreen?

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?


Answer
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).

Hope this helps.
