vble: problem with version check

[ami_stuff]

for certain resolutions vble codec writes something else than $01 as an version to the output file
(or at least $01 value is at the different place)

the binary codec seems to not care about version at all while decoding the file, so maybe a fix would be to remove version check from the ffmpeg's code
