Hmm, both were "budget" type cards, right? The data transfer on these cards
is a bit time critical... And to make things worse, there are still
chipsets being produced which are apparently not fully PCI capable: I
recently tried my TDA10045 card in a P4 machine with a SIS motherboard
chipset and found that when the SAA7146A used PCI bursts of more than 16
DWORDs, I would end up with CORRUPTED data in system memory. It seems to
still hold true that only Intel can produce properly working PCI
chipsets...

So - what's you PCI chipset, CPU, etc? And about that one mux you can
receive correctly, do its DVB-T parameters differ from the other ones?
Maybe it has a stronger error correction, so that its net data rate is
less, making it barely possible for your motherboard chipset to work
properly...?

You might want to take a look into your BIOS, if there are maybe some PCI
settings you can fiddle with...

Hope this helps,
