[FFmpeg-cvslog] vble: Do not abort decoding when version is not 1

[Piotr Bandurski]

ffmpeg | branch: master | Piotr Bandurski <ami_stuff at o2.pl> | Tue Nov 27 14:05:46 2012 +0000| [f5fa03660db16f9d78abc5a626438b4d0b54f563] | committer: Derek Buitenhuis

vble: Do not abort decoding when version is not 1

Some combinations of OS, VirtualDub, and VBLE can accidentally
set the version to a value other than 1. Since no other version
of VBLE was ever released, simply warn about it.
