In order to rule out a problem in VDR I have now created a TS recording
with a simple 'cat /dev/video > filename' (with the kfir driver loaded
with the above options). Even then only the first recording is ok. Every
following recording done the same way (after cancelling the current 'cat'
with Ctrl-C) shows artefacts. After re-loading kfir.o the first recording
works again.

This is absolutely reproducable here. Can somebody think of what might be
causing this? Could it be something in the driver that's not correctly
initialized or reset after the first recording?

Any help here would be greatly appreciated.
