It depends on the codec used.

From the above details Avi will have superior quality. Coz the Bit rate of video is higher and it uses H264 encoding

[Grr]

ok, i
ll go for AVI format, as I have large hdd..

AVI container also supports other codecs like Xvid and Divx, which are best known for their maximum compression. AVI + DivX/Xvid can result in good quality less output file size.

when i rip/convert mine.. i tend to do avi with xvid/divx.. and the qual is pretty good.. so that would be what i would go for myself
