Don't badmouth a format just because all you probably can find to download is aXXo movies
What format would you prefer maybe?
DVD maybe, which is 3 times the size and split into several files?
Mpeg maybe, which is a crap format sizewise and inferior to say the least?
WMV and MOV which are famous for spam + they are inferior also.
Which is it?
The only better formats are x264 formats.
Also cccp is a better codec pack:
Combined Community Codec Pack
