Which one is better quality: HR HDTV Xvid from CTU, or HDTV DVDR from BamHD? I'm trying to decide which one to get.

HDTV DVDR is better quality then HDTV Xvid but
1. dvdr is much bigger in size (4,7gb) while xvid is 700mb or maybe 1400mb
2. only if you have a really good trained eye you would see differences in quality cause xvid is also really good quality and the system they use to rip it (how much they can decrease the quality) has to do with human perception. dvd will be sweeeeet but a good xvid can also be sweeeeet (i did informatics in school). if you find the explanation confusing please tell me
3. the xvid you mean propably is a rip from a dvd so they will cut out the subtitles, other languages then english and extras. if you want these get the dvdr
if you have a max of bandwidth get the xvid, if you really cant live without the extras get the dvdr

Edit: My previous post wasn't really getting to the point Wink

HR.HDTV ir usually very good quality, check the nfo for the bitrate, take a look at the samples wich one you like best, however, CTU and TCM don't really care for quality. Also the quality depends on the signal the show was capped.

I haven't seen hdtv dvdr but I've checked hr hdtv once and I usually watch standard hdtv xvid, and the quality/resolution of hr hdtv is much higher. Isn't hdtv dvdr just hdtv with dvd quality (non compressed) but with dvd resolution and not hr resolution (720*xxx)?

edit:

So if my theory is right:

hr hdtv xvid - high resolution (720*XXX), hdtv source compressed with xvid codec, still same resolution, avi format
hdtv xvid - standard res (624*XXX), hdtv source compressed with xvid codec
hdtv dvdr - standard res, non compressed hdtv put on dvdr

If that's correct (?) i would choose the hr release off course. If you watch it through a high res tft tv screen It's recommended but if you have a tube based tv you should go for a lower resolution release.

i think that the addition of the DVDr is not related to the quality addition.
So i'd go for the xvid

As far as i know, you cant record at bitrate (not even close to) of a normal DVD.
HR HDTV xvid has 720*... max. That's the max resolution of a release. So the xvid has no quality loss when we only look at the resolution.
HDTV DVD has 720*.... But the bitrate will be slightly higher, but never forget, the bitrate can't be higher than the original screen quality. So i expect it to be around 2000 or so, which means it will have the double/triple size of a normal xvid.
When you are a quality junk and have no problems with BW, i'd say got for teh DVDR. but i still doubt that it will make it a 3 times better experience. there are still no subs, the best Q you'll get is tele quality, theres only 1 audiotrack etc etc. So why putting the effort in leeching something lot bigger?

I'd go for the hr divx Smile

It has been proven that xvid is much better then divx. It has about the same compression ratios, but looks much better in the end.

I think that Spankie just mistakenly wrote divx instead of xvid Smile. I haven't seen anyone use DivX in a looooooooooong time.

Maybe 3.11 but I don't see any major differences with the new DivX pro 5.21.

xvid or divx 5.001, people should understand that it has no substantial difference, no other algoritms.( both mpeg4) It just has another action/data ratio distribution.

anyway yeah i meant xvid instead of divx.

That's the problem for me. I hate switching discs. For extra material It's ok but not in the middle of the movie. Luckily we will have Blueray discs anytime soon so we don't need too switch and watch the movies with extremely high resolution and bit rate Smile.

It's more like a must to watch HR on such a screen. Standard dvd and hdtv looks pixelated on such screens.
