It did not help.

Should I still try the cx18-init-debug driver? Or could this indicate a 
problem with the board? I don't have WinXP on this computer, but I do on 
the old computer. Perhaps I should see if the board can tune and record 
channel 29 in WinXP on the old computer?

FWIW, when I verified that modprobe -r cx18 did indeed remove the cx18 
modules via lsmod, I was surprised to see some cx88 modules. I didn't 
think the HVR-1600 needed them. Maybe for the IR device?

Thanks,
Helen
