My latest mailed patch that I use makes sure 0x47 is found at demux->tsbufp[0], if there is at least one spared byte. Otherwise the resulting 188 sized packet would be discarded eventually. It would be good if Mauro would accept my patch for dvb_dmx_swfilter(_204) functions some day. It increases robustness with garbage input, and performance by avoiding unnecessary packet copying. > dvb_dmx_swfilter_packets() expects complete TS packets from the driver. > The saa7146 does so.

I'm delighted to hear that ttpci is so well implemented and tested and so long :) I was very impressed in the quality of the code with dvb_dmx_swfilter_packets(): so simple and efficient. Unfortunately I have had lots of problems with Mantis. But because of that, I've learned DVB driver programming. H.264 works now mostly in one TV channel without crashing Xine with remote vdr. I had to modify streamdev plugin too for vdr.
