Ha, so simple.  I thought I looked everywhere for the documentation and 
it was under my nose all along.  Thanks

However, I now have a partly working card, but I have a couple of major 
problems still

a) no sound, either from the sound jack on the back of the card, or from 
the /dev/dvb/adaptor0/dvr0 device (if I pipe it to mplayer via "ts2ps 0 
0" then I get a picture, but no sound)

b) after changing channel more than a dozen or so times the driver 
appears to lock up, picture disappears from both TV output and also 
/dev/dvb devices.... No errors in the log, everything still "appears" to 
work fine, just no picture...

This also happens quite repeatedly under vdr, and doesn't appear to be 
dependent on visiting any special channel, eg just flick backwards and 
forwards on the first couple and eventually the picture disappears, but 
menus still pop up, vdr logs channel change events to syslog.

tzap still appears to work ok, but "cat /dev/dvb/adaptor0/dvr0" doesn't 
give anything....

Running "rmmod dvb-ttpci alps_tdlb7 dvb-core" brings everything back to 
life for a few more channel changes.

Does anyone else experience this?  Any suggestions on how to debug this 
further?

Thanks for any help
