Dvds come out with choppy edges/motion!

[venomous BMz]

Ok so ive had my mac for about 3-4 months now, I love it like hell definatley better then PC never had any problems with it breaking down or anything. Always runs smooth etc...

My problem is DVD burning I use DVD-R JVC and they burn fine ( I use iDVD and Toast Titanium). The problem is that my DVD's always seem to come out choppy, Ive been trying to fix this problem for months and i can't seem to figure out what it is...
I burn AVI's to dvds and watch them on a 27" LCD. Well i thought to myself maybe its the TV? Nope i tried all the tv's in my house same result. I even plopped it in my Imac g5 and it played with the choppy edges. These choppy edges appear very distinctly when there is a lot of motion in a film. Today i tried something new i exported a sample clip to .MOV from .AVI and it seemed to look perfect like it should when i burned it to a DVD.
So is the problem that my Mac doesnt burn .AVI's clearly, I guess it will only burn .MOV. I do have friends with Imacs and they dotn h ave this problem at all, Its really upsetting cause it takes about 10 hours for a 2 hour movie to export to .MOV just to burn it. I would be pleased if you guys would please tell me an answer to this, because choppy edges ruins my whole movie watching experience. I know there has to be something that is not letting me burn .AVI's correctly to DVD. I really hope this isnt a internal problem with my DVD burner cause new external ones are about 200 bucks. Could you guys please look into this for me,

Thanks all help appreciated, Kevin L. Oregon

DVD's use the MPEG-2 standard for video encoding/decoding. this means that when you put the AVI onto the dvd, and burn it off, what it's actually doing is cross-coding the AVI into MPEG-2. when ever you reencode compressed media (be it MP3 to WMA, Jpeg to Jpeg or MPEG4 to .Mov, etc), the quality will suffer. this is unavoidable. what you can do, though is try and boost the quality in the encode. what do you use to encode to dvd?

also, try FFMPEGX to crosscode, it's a damn sight faster than Quicktime, and has a lot more codecs availabe to it.

what do your friends use to burn dvds?

Wow... sorry for the very very late reply... no replies were showing up till now for me? Kinda odd. Anyways to answer you questions... My friends burn with Toast Titanium as well. My DVDs to this date come out with choppy edges in Toast and IDvd, however... I found a alternative.The program called "Burn" for osx encodes the Avi's/media into Mpeg2 DVD media and it plays crisp with no choppy edges. Problems is it tends to be a longer alternative to burning dvds then toast is. So i really wanna figure out whats up here... My friend has his Toast Titanium on the same settings as me! But his come out fine. I really dont know what could possibly be going on, whatever it is it's anoyying the shit out of me lol! I really need to figure out whats wrong with Toast and IDvd, I honestly dont think encoding it to anything different in FFMPEGX will have an effect when i burn in toast. Anybody who wants to help me get down to the bottom of this please feel free to.
