Will try that.. But newer DVB drivers (or newer kernel 2.6.15) seems to 
break HDTV for me..

The delay is now set to 500msec (was 0 before), here's a output of the 
log file. Hope it helps. I can't really increase the delay time until it 
works, coz most of the time, it will work (only 1 in 15-20+ recordings 
will fail)... Will continue to monitor to see if any fail recordings 
turn up or not..
