Is this slave backend?

If so, were the clocks on the master and slave in sync?

Other than that, this looks suspicious:

2006-05-26 09:46:28.433 0xacdfbbb0 bool
DVBRecorder::ProcessTSPacket(const TSPacket&) DVBRec(1): PID 0x40

DVBRecorder::WritePATPMT() Writing PAT & PMT @7b6f0a54 + 19e30523

DVBRecorder::StartRecording() DVBRec(1): Resetting Demux Filters524
2006-05-26 09:46:28.443 0xacdfbbb0 int debug_thread_create(pthread_t*,
const pthread_attr_t*, void*(*)(void*), void*, const char*, const char*)
PTH: Created run_dummy_video(0xa8a6bbb0) from StartDummyVideo

The discontinuity itself could be due to some problem at the
transmitter, or reception problems, so it's not so fishy, but
this is not the PMT for our program, so the demux filter reset
looks strange.
