I agree. Though there is some kind of a release note in the doc, it
still contains outdated information. (Also it is not quite complete. 
So I had to look into the driver sources for the ioctl's)

There is a simpler method. If you press on the penguin in tuxzap 
you can use /dev/ost/dvr for recording and playback with "cat".
The recorded channel is set by tuxzap. The data format is TS.

AFAIK, PVA streams were still supported in 0.8x

I am running dvb-20010604 with modified VDR-0.97. Helps me keeping the
audio sync'ed when replaying my recordings... ;-)
