I notice from your lspci output that you are using the same/very
similar chipset as me (I am using an MSI Hermes 650 box).
The IDE interface identifies itself as an SiS 5513 which was
an old SiS chip! This means that the driver does not automatically
enable DMA. I don't know if this may be you problem. It
certainly has an effect on the record/playback performance
that I see.
Look at the man page for hdparm, doing something like
hdparm -t /dev/hda
will give an idea of the disk speed. After enabling DMA with
hdparm -d1 /dev/hda
the disk speed give by my system went from 3 to 50 MB/s!
Hope this help,
Simeon

Hi,
I've got quite the same problem but using VDR with only one DVB
card. The picture is getting pixelized with sqares during 1~2
seconds. Sometimes the screen goes black.
I've try several driver version, the result is the same :-(
Tested driver:
DVB-cvs-20030102
DVB-cvs-20030116
linux-dvb.2002-12-01.tar.bz2
linux-dvb.2002-12-08.tar.bz2
linux-dvb.2003-01-08-ci-ll
Playing with the latency does not fix the problem.

Subject: [vdr] PCI Latecy and OSD?
vdr 1.0.4 AIO, 2 full DVB-s with single irq for every card)
as i had problems with my 2 DVB-s cards (picture distorsion on
card1 when
recording on card2)
i tried to increase the pci latency from 32 to 64 and had so
effect - only
the impression that the typical OSD problem (lower quarter somtimes
missing
and wrong colors) increased
so i decresed the latency to 16 and had significant less OSD
problems then
with 32
Did you try a latency of 128? The DVB-cards need it at least.
