I had the same problem here. The cards stayed tuned, EPG data for the 
tuned transponder was updated, but recordings didn't work.

I'm using VDR on Fedora Core 4 and built a custom kernel based on the 
original from Fedora plus your patch.

Great work, Patrick!

I have VDR 1.3.27 with two AirStar2 PCI cards, it seems to work now! VDR 
is running for about 6 hours with the patched kernel and the EPG still 
gets updated. I've recorded some programs in the meantime to see 
whether it still works afterwards, no problems so far.
