I spoke too soon - The system I'm working with is intended to have a 
PVR350 (ivtv) and a pair of Nova-T's DVB (cx88) and hopefully at some 
future date a DVB-S card.

I'm on kernel  2.6.18-194.8.1.el5.centos.plus, which includes the cx88 
driver. The previous kernel,  2.6.18-194.3.1.el5.centos.plus, 
accidentally had the cx88 driver missing.

If I load the ivtv driver rpm that I built, based on atrpm's sources, 
for 2.6.18-194.8.1.el5.centos.plus and then load the video4linux rpm I 
built the video4linux one de-installs the ivtv one in the process of 
installing but I get the PVR 350 working in Myth

But....

I'm transitioning from 'soon' to be de-comissioned FC6 myth system. I 
swapped the Nova-T's (which had worked before) into the new box 
alongside the pvr350 and found that if I try to load the cx88 driver I get

  modprobe -vv cx88-dvb

If I remove the video4linux rpm and replace it with just the ivtv one 
the cx88's work again but I get the same behaviour as I got from the 
pvr350 when I simply compiled up the two ivtv.ko modules from the ivtv 
driver tar.gz package. Ie: Myth isn't interested in working it.

I notice that most of the complaints above are about new modules that 
come from the video4linux rpm. In my researching the error I saw some 
comments about compiler differences. gcc on this box is 
gcc-4.1.2-48.el5. And uname -a says "Linux  
2.6.18-194.8.1.el5.centos.plus #1 SMP Wed Jul 7 11:45:38 EDT 2010 x86_64 
x86_64 x86_64 GNU/Linux"

I know this is a kludge, but what bits of the video4linux package are 
really needed to get the pvr350 working in Myth. Could I strip out 
what's not required?

Any ideas for unravelling/progressing this further.

Thanks

Ken
