[vdr] Too many open files?

[Gavin Hamill]

Hi - I am trying a vanilla 1.3.37 (same issue with 1.4.0) with a USB 
DVB-T stick (a Freecom-branded Wideview 220 clone) which works perfectly 
with vlc, dvbstream, Kaffeine, etc.

If I run vdr, and then just try to record the current channel, I get this:

Jun  5 13:48:59 telly vdr: [11315] switching device 1 to channel 21
Jun  5 13:48:59 telly vdr: [11315] ERROR: can't open filter handle on

It would suggest that the number of PID filters on the device has been 
exceeded, but I know that there are 15 available, and VDR is only using 
nine:

root at telly:~# lsof -n | grep adapter0.demux0  -c
9

BBC News 24 has a channels.conf entry of 
754166670:C34D34M16B8T2G32Y0:T:0:640:641=eng:0:0:4415:9018:4104:0

so it's only using two PIDs.

I have verified that the device truly does have 15 PID filters available 
thusly:

dvbstream -f 754167 100 17 600 601 610 611 612 613 640 641 650 651 652 
1013 1021 -i 127.0.0.1
FE_STATUS: FE_HAS_SIGNAL FE_HAS_LOCK FE_HAS_CARRIER FE_HAS_VITERBI 
FE_HAS_SYNC
Setting filter for PID 100

Setting filter for PID 613
Setting filter for PID 640
Setting filter for PID 641
Setting filter for PID 650
Setting filter for PID 651
Setting filter for PID 652
Setting filter for PID 1013
Setting filter for PID 1021
Using 127.0.0.1:5004:2
version=2
Streaming 15 streams

and adding another PID to the list gives:
FE_STATUS: FE_HAS_SIGNAL FE_HAS_LOCK FE_HAS_CARRIER FE_HAS_VITERBI 
FE_HAS_SYNC
FD 15: DEMUX DEVICE: : Too many open files

Can anyone suggest why VDR might be receiving this error?

Cheers,
Gavin.
