	demux_mpeg_block.c 
Log Message:
That comment suits better here. It is about discontiuity detection, so it should
be close to the funtion doing this.

-/* OK, i think demux_mpeg_block discontinuity handling demands some

-   - Has been shown that sometimes a DVD discontinuity may happen before

-   if NAV packets have already done the job.
