[vdr] Two cards, only one works

[Jamie Honan <jhonan@optusnet.com.au>]

I hope someone can point me in the right direction with my problem.
I've spent many a long hour on this to no avail!

Short description:

I have two cards in my slowish system, one satellite and one
terrestial.

The satellite card behaves perfectly under vdr; the terrestial audio and
video 'stutters' unusably under vdr, but behaves perfectly with mplayer.

What I'm hoping for is someone to point me to some places in the
vdr or driver code where I could put debugging messages to help me.

Long details:

vdr-1.2.4 and vdr-1.2.5
kernel 2.6.0-test7 with recent dvb-kernels from cvs
system : amd 200 Mhz
satellite card : dst FTA
terrestial : Nova-t (budget-ci)
playback : dxr3 for both mplayer and vdr

Attempts to rectify problem so far:

increase ringbuffer to 20 Meg (eliminates ring buffer overflow messages
but does not help breakup / stutter)

#define DO_REC_AND_PLAY_ON_PRIMARY_DEVICE 0
#define DO_MULTIPLE_RECORDINGS 0

Try taking satellite card out and / or disable satellite
dvb driver : no difference

Examine driver:
no overflow messages in dmxdev
in any case, satellite works, mplayer works with terrestial

Other information:
The satellite frequency has a large number of streams, only one
FTA which I use. The problem appears to be worse on certain terrestial
channels than others, perhaps ones with less streams of data?

Sometimes one particular channel in vdr will 'lock' quite well for
a while, the others are always unusable.

The way I use mplayer is to use tzap to tune, then attach
mplayer to the /dev/dvb/adapter1/dvr0

The nova has a remote control. If I use this in vdr it breaks the sound
up badly (like a screech). Keyboard used as a remote doesn't cause
problem. With tzap / mplayer, the remote doesn't cause any interference
at all (can still see rcu events with evtest on /dev/input/event1 while
mplayer running). I think this means, again, that the driver is probably
OK.

Thanks for any suggestions
Jamie
