Hi, I have a Hauppauge/Nexus-s rev2.1 and a Nova-CI-s rev1.0 running with VDR. my cards are plugged to a SAT-Multiswitch with 8db damping. the cables are 5-6 meter long. from my multiswitch to my LNB (only Astra 19.2) I have about 25 meters of cable length.
2 weeks ago I decided to buy new hardware (celeron 2.4GHz, MSI-6850, 256MB RAM, enermax-power supply) until this point I used an old Asus-P2L97 with 433MHz(Celeron/P2). This system runs without any problems for 32 month. After switching to the P4 system, the cards produced ongoing distortions, even on live-viewing. So I tested several older hardware again: P2 Celeron 433MHz ( no distortions ) P3 850MHz i440BX ( only few distortions ) P4 2.4GHz i845GE ( lot of distortions ) I fiddled around with pci-latency-settings, triple checked the io system, swapped pci-slots but it's simply not stable. I searched around in the list-archives and found people who has/have problems with dvb-s cards, too. One suggestion seems to lead to the power-supply. The cards seem to get unstable, if it get's not exactly 12V power supply. Since Intel-CPU's are mostly 12V-hungry, that could be a problem. Some people said, they had no problems with AMD-systems. AMD-processors are 5V hungry, so this could be an explanation... Is this a known stability-problem with dvb-s cards ? What can I do to cure the problem ? (I don't want to buy AMD or special power-supplies, if I'm not really forced to :) Thanks for any answer ! --Andi -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe linux-dvb" as subject.
