[vdr] Re: PCI Latecy and OSD?

[alexw <alexw@undercover.mine.nu>]

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.

Here is the lspci -vvv

I am using VDR version 1.2.21. This soft rocks ;-)
