[mythtv] Ticket #1970 (dvbrecorder: limit number of open pid filters)

[John Pilkington]

This is marked as a closed patch: fixed, and has been applied in mythtv 
0.20, but I still see what were, I understand, the original symptoms.

I have reported this earlier on the ATrpms user list.

When recording a program, mythbackend reports, about every two seconds,

  DVBRec(0) Error: Could not open demux device.
                         eno: Too many open files (24)

The recordings produced are excellent, as is the EIT program guide.

I'm running FC5, fully updated via the ATrpms repo, and using the 
Freecom DVB-T USB pen receiver in the UK.

Here are two sections from the system log:
------------

Receiver (Typhoon/Freecom)' in cold state, will try to load a firmware

Sep 29 08:32:45 localhost kernel: dvb-usb: WideView WT-220U PenType

It would be nice to have this fixed, although I'm not sure that it is 
causing any real problems.

It could be worth mentioning (?) that I also use a USB modem:
  [ueagle-atm] ADSL device founded vid (0X1110) pid (0X9032) : Eagle III

Thanks in advance,
