If I put the sample through avimerge, the resulting file is fine. So
transcode's demuxer seems to handle it fine.

If I process the sample with
mencoder -demuxer lavf -of avi -oac copy -ovc copy -forceidx sample.AVI -o sample.reindex.avi
the result also plays fine, despite messages about skipping frames. I
didn't investigate the quality though.

Interestingly, the original sample plays fine in Media Player Classic
(on Windows), but I don't know which demuxer that uses.

Is this of any help?
