Still pictures from DVDs

Does anyone know of a program that can make high res still images of DVD movies.

I tried just playing them in my computer and taking screen shots, but for some reason on my computer when you take a screen shot of a movie the movie screen just turns out black.

and besides im would actualy prefere higher resolution pictures then just what a screen shot would give me.


PS: i dont really care if its illegal

screen shots dont work in windows cause of the way the image is overlaid onto the screen by winblows when playing video

vlc media player will take snapshots at native resolution, you arent gonna get hi res, 720x480 NTSC or 720x576 PAL

One cannot fight mathematics and win. The video stream only has so much quality in it, and that's that. No matter how you do it, you won't get high quality images from a video source that's inherently low quality. Sorry. Yes, you can get a huge resolution through interpolation, but it won't have any more detail than the image you started with.

When its on my flat panel computer monitor is appears to only have so much quality......but how come you can play it on a normal Television and have it crystal clear 3 times as large as my computer monitor?


Edit:the DVD is a professional one of the 2005 DrumCorp World Championships so i figured it should be capable of producing extremely nice pictures if you know how.

VLC's the sh|t!!! I even use it as a juke-box to broadcast videos across my network to a large-screen TV in the living room.

actually VLC is so, so, you want "the sheot" get mplayer/mencoder on linux, that can do just about anything, many things VLC wont do

there is a version of mplayer/mencoder compiled for windows using cygwin, and it does work, but there are some features missing that only can be done with linux

As far as why does the picture get bigger and look better on a TV, the reason is quite simple, the number of horizontal scanlines on a TV is fixed and stays the same regardless of its screen size, it also in effect hides alot of errors so to speak, you cant see what it wont show On a computer monitor its done a bit differently and monitors have vastly superior resolution.......so typically the picture gets expanded to fit it which causes pixelation and other issues, most of which can be very well hidden or masked by a good quality player and decent source. The harsh reality is, TV's suck, and suck BAD compared to a PC monitor, problem is, the source for video isnt very good either. DVD resolution is only 720x480 or 720x576 depending on where you live. Even HDTV doesnt add that much as the ultra hi res stuff promised by the industry a year or two ago still doesnt exist, and its looking like it might never happen.

A few reasons. As pedex notes, TV quality sucks, so you're used to seeing a lower quality there, and you're not as picky. Also, you're generally sitting a lot further away. There's other reasons, too, but those two are biggies. Try looking at a TV at the distances you look at an LCD screen and telling me how that DVD looks!
