MP4 is what I have used for the longest time as it's pretty cross-platform friendly. Works on my 9930, Playbook, all PCs of course, PS3, PSP, Android, and the iPod I used to have.
I think that's enough random things to throw in there.
Quality has always been acceptable for me
hi there does anyone use any video converter? i see that there are two options....it lets you chose different frame sizes and also video bitrate.... anyone know what the best options are for the 9900?
