lotr.mov plays correctly in QT 7.0.0 and 7.1.2 on Mac OS X. I found a
H.261 decoder in the QT DLLs with the help of Compn on IRC that worked
flawlessly on x86 Linux with MPlayer's native demuxer, but it fails with
libavformat. So lotr.mov should be a valid file, but the libavformat
MOV demuxer is still buggy about it.
If you think that h261test.avi is completely broken then we should
possibly remove it from our samples collection.
