[Mplayer-dvb] Reproducible MPlayer Crash with dvb-t card

[David Maslen]

Hi All,

I think I need a bit of help to know how to report this bug. ie Strace
or other tools.

It may not exactly be a mplayer bug, but I can reproduce it with
mplayer and not with any other program on my system.

I have a Avermedia DVB-T card. It's working on my debian system with a
V2.6.5 kernel. The system is a Celeron 1400, with aprox 380M SDRAM, on
an older Asus P2B-F motherboard.

Below is a cut and paste from a screen session.  It shows me dumping a
stream to disk. It starts to save. Then I jump to another shell (via
the network) and run a disk intensive command like find /

The Mplayer session immediately ends, and won't start again until I
reload the kernel module dvb-bt8xx. (rmmod then modprobe).

I did record a show while watch another last night (at the console not
across the network), which makes me think it might not be disk access
or cpu load. I think it could be related to network access, as running
a P2P file sharing application or transferring a large file across the
network also seems to have the same effect (ie. cause a crash).
