Hi!
I tested Euro1080 HD5, an MPEG2 HDTV test program, using these commands:
1) mplayer dvb://HD5
2) mplayer dvb://HD5 -cache 1000000
3) mplayer dvb://HD5 -dumpstream &
mplayer stream.dump
4) mplayer dvb://HD5 -demuxer lavf
5) mplayer dvb://HD5 -demuxer lavf -cache 5000
I used -vc ffmpeg2 for all tests, because mpeg12 stays quiet on decoding errors
and hides them much better; however, the same errors happen for both decoders
(and ffmpeg12mc), it's just more difficult to notice with mpeg12.
1) mplayer dvb://HD5
Repeatedly shows these messages together with ugly artefacts:

(This never happens for SDTV streams)
2) mplayer dvb://HD5 -cache 1000000
same errors as 1)
3) mplayer dvb://HD5 -dumpstream &
mplayer stream.dump
Works without any errors: That's why I can't upload sample!
4) mplayer dvb://HD5 -demuxer lavf
Doesn't work at all: Fast A/V desync, then freeze.
5) mplayer dvb://HD5 -demuxer lavf -cache 5000
Works!
I'm testing 1) and 2) since months, only found out this week that it works with
-demuxer lavf (and today that it's not possible to produce a sample). I thought
before that something might be wrong with the stream.
Ideas? Any other information I can provide?
