The following message indicates the problem. Unfortunately, ffmpeg (or
any other open source decoder) does not support interlaced VC1
decoding and I don't see it happening anytime soon.

Your only choice is to convert to another format and you probably will
need to use a Windows based tool (ie. RipBot264) to do so.

Luckily interlaced VC1 isn't very common.
