h264 interlaced decoding failure - alot of artifacts and error log messages

[Hendrik]

Following file fails to decode properly:

​http://files.1f0.de/samples/20100812_1635_-_TVNorge_HD_-_Gossip Girl.ts

The file is a DVB-S2 recording.

The problem can easily be reproduced with ffplay.
Seeking in the file sometimes fixes the problem, which strikes me as odd.

I realize the file is problably just broken, however since seeking sometimes fixes the problem, maybe the error can somehow be concealed while decoding?

Attached is ffplay output when decoding.

Correct link to the sample:

Sorry about that.

Works fine with the reference decoder and mplayer -demuxer h264es, fails with mplayer -demuxer lavf
