[vdr] AW: Re: Audio+Video getting out ouf sync while replaying?

["Seeberg, Ingo" <iseeberg@gmx.de>]

Hello people,

it's really annoying because VDR crashes very often during fast
switching operations, ie. cutting oder fforward.
Got the same problem and as far as I know there isn't even a workaround
is there?

VDR works great during normal operation and the patches available are
very usefull.

I have to apply some patches this weekend - let's wait till then :-)


Greetz - and thx for so much work (@ Klaus and others...)

	Ingo

I believe it means that the firmware in the ARM processor on the card
has crashed.

A friend of mine is seeing this very often during normal
use of vdr.
I can reproduce that error easily when editing vdr recordings (see the
list archives). It also happens here when I switch between play, pause,
fast forward and fast reverse too quickly.

I tracked the problem down once and found out that a certain OSD ioctl
is always the last command to the dvb driver before the ARM crashes.
Unfortunately, the driver developers have little interest in the OSD, so
it is unlikely that they will fix this.  :-( IMHO, it is the most
annoying remaining bug.

Carsten.
