I can also confirm that the pre-emptions I see with a Geforce 9400 GT PCI with 190.42 when receiving DVB depend on the motherboard model: I can reliably reproduce the pre-emptions on two Epox EP-8KA3+ Rev 1.2, BIOS 2003/04/09 (Athlon XP 2600+ 2GHz), with three different DVB cards: Two STB0899 based (KNC1 DVB S2+ and Technisat Skystar HD), one SAA7146 based (KNC1 DVB-T). It does not matter how I set the following BIOS options: "PCI Latency Timer" (did not try many values), "* Cacheable", "PCI * Write", "PCI Delay Transaction" and "Init Display First".
I have never seen an option to disable AGP on any board and "Init Display First" usually makes no difference for me.
I do not get any pre-emptions on a pre-2000 Pentium III board (P3-500) watching HDTV for several hours using the same graphic card and one of the DVB-S2 cards. Note that on this board, the graphic card is not recognized (and not started) by the BIOS which does not matter because the graphic card is started when X starts (I have an AGP graphic card in the system to see startup messages and to be able to use the console, but X/VDPAU also works without the second graphic card).
