[MPlayer-users] mencoder crash on tv

[WK <sprawki@xxxxx>]

I have got crashes of mencoder versions pre9 - rc1 and all cvs.
It happens on tv input.
I am not sure - is that by my kernel module, glibc or just mencoder bug.
I attach gdb backtrace. Options are minimal, but it happens independent 
on configuration.

I would gratefull for any solutions.
