[linux-dvb] PCM syncing

[Ralph Metzler <rjkm@convergence.de>]

Hi,

I added a crude syncing mechanism for PCM playback to the firmware.
First tests playing back a DVD with PCM sound are promising.
Previously sync was often lost when freezing and continuing 
the playback. Now it always stays in sync.

To take advantage of this in DVD playback you will have to insert
the PTS of the initial AC3 PES into the PCM PES. 
The total PES length still must not exceed 2048 bytes and it seems
that the actual PCM payload (after PES header and PCM header)
has to be word aligned to the PES start for the AV7110 to correctly
swallow it. So, add padding to the PES header if necessary.

Ralph
