[linux-dvb] Problems fetching multiple channels from the same dvb stream

[Kimmo Mustonen <kmustone@cc.hut.fi>]

Hello!

I have Hauppauge WinTV Nova-T DVB-T PCI card and am using dvbd-0.7.2 and
linuxtv-dvb-1.1.1 and kernel 2.4.26 (SMP, hyperthreading P4@3GHz).

At first I thought that everything is working fine but suddenly something
failed while saving two channels from the same stream at the same time. I
had tested that before and it is mostly working, but I can reproduce the
problem easily be trying to save three channels simultaneously. The first
two channels started to save work fine but the third one after those seems
to fail every time and no data is saved on disk. In dmesg, the following
lines are output:

---8<---8<---
...

dvb_demux_feed_del: feed not in list (type=0 state=0 pid=ffff)

The last two lines are repeated every time I retry saving the third
channel. I guess the problem might be in the linuxtv-dvb, not in dvbd...?
Any suggestions? I didn't find any newer CVS snapshot in the homepages
so I couldn't try those. I tried google and searching the mailing list,
there were similar symptoms but they didn't seem to be caused from the
same reason, or at least it was not obvious.

Otherwise the system seems to work quite perfectly, even though the tools
I'm using are far from being too user-friendly, at least not for dummies.
