The IRQ for the SkyStar 2 was shared. I intended to mount it in a slot with 
unshared IRQ, but that one is currently blocked by a cable that connectes my 
externel power supply fan control circuit with motherboard and power supply.

I'll try that soon.

Please tell me the brand of your cards.

How did you realize, that the cards were defective?

Currently, my Nova-S shows a strange behaviour again: within the first 30 
minutes after powering on my "cold" VDR PC, there are that many uncorrectable 
errors on any vertical transponder, that watching TV or recording anything 
makes no sense. Horizontal transponders work properly from start. While the 
system "heates up", one can see the images improving and after 30 minutes 
everything is fine again.

I already thought about sending the card in for repair (I've bought it last 
September), but I only had this issue for one week in late November and 
yesterday evening. I can't tell any news for today, because the machine was up 
since yesterday to take a recording this morning (still haven't tried the 
plugin that programs the RTC for starting the PC just before a recording).

Well, in my desktop PC case, the slot area is near the left side of the case, 
and close to the slots there follows a fan at the rear side, that blows out 
hot air from this area.

The case temperature sensor is currently located above the center of the case, 
just below the case cover. I'll try to move it to the slot area, to see 
whether there is a higher temperature.

I've also constructed an "air tunnel" that feeds cold air from the outside to 
the cpu fan. This construction had a great impact on keeping everything a lot 
cooler, and therefore, all fans typically run at minimum speed when watching 
TV (I'm using the vdr-xine plugin).

Shure. It's really a mess, when all those "fat" cards are that near together, 
with no empty slot between them.
