No, it's a hardware-patch, but the driver has to be adapted to use it (and co-operate the direct frontend-SAA7146 connection of the patch-PCB and the DEBI-port with the AV711x). > > Anyway - it would be great if someone could tell the list the difference > between "filtered" and "unfiltered" TS.

The full-featured card cannot provide full TS as it lacks bandwith (and TI didn't implement that). So, to get a TS out of the card, it has to demux the PES-Pids from the TS and remux it into a new TS. But the number of Pids is limited. > > When doing so it ignores the PTS used for A/V sync -- either because they > are already correct in the "filtered" TS (but then what about unfiltered > streams from budget cards) or because it's reckoned that PTS is not needed. > Could someone please enlighten me on this issue? Usually full-featured DVB-S have hardware-oscillators to determine playback-speed. So you only need PTS for SW-playback.
