Can someone with both a PVR-350 and a PVR-150 (or another card with a
cx2584x chip) test this? I get the feeling that it works on a PVR-350
but fails on a PVR-150. BTW: it seems to work fine as well for a
HVR-1600 (cx18 driver).
I am abroad from Wednesday until Sunday so I do not have time to test
this myself.
Regards,
Hans
