[vdr] VDR ERROR: can't set filter every 20 seconds

Hi

My cable provider recently made a number of changes to channel allocations, and since then I'm getting the following errors every 20 seconds or so:

Dec 6 10:57:14 callin vdr: [20844] ERROR: can't set filter (pid=16, tid=40, mask=FF): Device or resource busy Dec 6 10:57:35 callin vdr: [20844] ERROR: can't set filter (pid=0, tid=00, mask=FF): Device or resource busy Dec 6 10:57:35 callin vdr: [20844] ERROR: can't set filter (pid=17, tid=42, mask=FF): Device or resource busy Dec 6 10:57:35 callin vdr: [20844] ERROR: can't set filter (pid=16, tid=40, mask=FF): Device or resource busy Dec 6 10:57:57 callin vdr: [20844] ERROR: can't set filter (pid=0, tid=00, mask=FF): Device or resource busy Dec 6 10:57:57 callin vdr: [20844] ERROR: can't set filter (pid=17, tid=42, mask=FF): Device or resource busy Dec 6 10:57:57 callin vdr: [20844] ERROR: can't set filter (pid=16, tid=40, mask=FF): Device or resource busy Dec 6 10:58:17 callin vdr: [20844] ERROR: can't set filter (pid=0, tid=00, mask=FF): Device or resource busy

There seems to be the same repeating pid/tid numbers: pid=16, tid=40 pid=0, tid=00 pid=17, tid=42 pid=18, tid=60 pid=20, tid=70 pid=18, tid=4E pid=18, tid=50

I have FF-2300 and budget C1500 TTcards. It seems to be affecting both. Symptoms are intermittant no lock on channels?

Any ideas what this is??
