What he said.

Commercial DVDs are encoded at the previously mentioned resolutions, but they also support some lower resolutions - 352x240, 352x480 (NTSC) These resolutions aren't really used though ... except by me when I was sneaking easter eggs onto a full DVD I authored >_>

I've heard people say they added easter eggs onto dvd's...what does that mean?

thanks for the reply's, but if dvd's are that high of resolution, then how come when you download(hypatheticaly) a dvd rip form the internet its at lower res?

Then whoever did the rip/encode (you would probably not use MPEG2 for online distribution, as the files are enormous relative to more modern formats like MPEG4) lowered the resolution. The files start at 720x480 (although the bitrate can vary considerably between movies, from ~3-4Mbps to ~9Mbps).

ic, so pretty much movies that i watch that are actually on DVD are generally gonna look way better than if i downloaded(hypathetically) them right?

Hypothetically, it depends on how the re-encoding was done, and what the bitrate of the source and output files are. It's possible to do near-lossless rips to MPEG4 (or other formats) -- but you'd have a 3-4+GB output file, which is a tad large for online distribution. Obviously, if you take a movie and crunch it down to 700MB, it's going to look like crap.

well, hypothetically, if i were on a university lan and was able to dl from another university pc at about 10-15mbps average, then it shouldnt be a problem right? dvd quality movies hypothetically should work?

i get what you're saying..thanks alot for the help
