Yep. I'm quite happy with this.


The current issues are:
- video lag of 1/2 to 1 second to audio, i.e. no lip synchron audio.
- sometimes block artefacts, but this could be related to the digital TV signal. Or maybe an MPEG stream of 5MBit/sec. can not be handled that fast.
- on some channels no video but audio decoding, i.e. listen to black screen. This is reproducible. I wonder, if some channels give a different MPEG stream. Please tell me if you need some more information or debug output. Currently I did throw out all printf() to put down CPU load. The only debug I noticed is, there were just audio messages but no video synchronise messages.

Right now the CPU is at approx. 45% load during video decoding.
