[vdr] searching a HW problem

Hello,

i have a VDR up and running, the SW works fine so far (at least i think so).

Some recordings are half-corrupted, have breaks inbetween, bad sound, etc.

The bad-quality problem is not related to a certain channel, i wonder how i can track this down.

My hardware: 2 (TWO !) Terratec Cinergy PCI cards. <-- two cards MSI C847 MS-E33 board

I use DVB-C.

The cable goes into me set-top-box, out to PCI card 1, from there out to PCI card 2.

I wonder if i can detect somehow which card did which recording?

Is there a way to force a recording to happen on a certain card?

Thanks for any hints Torsten
