Hi guys!
I have a few home shooted videos in DV-AVI format. I want to convert them to XVID format. What is the best Video Size in which I should encode it. I want to see the final output on a 29" CRT TV. As a video in DVD format is different than that of VCD format and both runs fine on a TV, I am not able to decide which size gives the best output on TV. Please help.
Thank you.
Best video size for CRT TV???

If the tv is 4.3 then you want a 4.3 PAL/NTSC sized file so 720x576 (720x480)
If you have a widescreen tv then it needs to be 16.9 PAL/NTSC (still same sizes 720x576 etc)
The compression from dv.avi to mpeg2 for dvd is far less than that for vcd mpeg1, so I'd say go for for mpeg2 dvd, you can get an hour movie on a dvd using mpeg2, you can get an hour movie on a CD using vcd mpeg1!!!!!!!!!!!!!!
Then you say you want to use xvid, so you could use any compression you like, does your player play xvid files?

A standard PAL DV-AVI file will be 720x576, so that's the best you can do (Increasing the resolution won't improve the picture quality.) And, that's the best resolution allowed on a standard DVD.
A higher bitrate will give you better video quality. Since most of us are not altering resolution, bitrate is usually the most important factor! If you are going to use low bitrates, Xvid should give you better quality than a standard MPEG-2 DVD. (Personally, I don't mess-around with these highly-compressed formats. I'm usually just trying to make regular DVDs that conform to the DVD standard.)
When you buy a commercial DVD, it will be encoded as 720x576 MPEG-2 and will typically have a bitrate around ~5500kbps (Bitrates vary).
If you have a standard definition TV, there is no advantage to using a HD file.
If you have a high-definition DVD player, it might play HD Xvid. But, Xvid is not part of the DVD spec, so you'd have to check the specs for your particular player.
If you are hooking-up your TV to your computer, you'd need an HD video card to get better than standard resolution.
