Talk:DVB-C PCI Cards
Do you know if the techinsat cablestar 2 DVB-C PCI Card is supported ?
I reverted the following addition because it seems that it addresses general compatibility problems as well as a very specific combination of hardware.
- Hardware Compatibility Issues: Some motherboard chipsets are known for hardware incompatibilities with several PCI cards. Depending on motherboard chipset, BIOS, driver versions and connected PCI cards, it could be necessary to change the PCI latency of the DVB-C card or the latency value of other PCI cards. Acoustic and image interferences appeared for example with a TechnoTrend C-1501 and an ASUS M2A-VM motherboard (AMD 690G/ATI RS690 chipset, BIOS Revision 0701, one USB PCI card with NEC chip, Linux kernel 2.6.27) after 10 to 30 minutes playback. The error message "kernel: saa7146 (0) saa7146_i2c_writeout [irq]: timed out waiting for end of xfer" occured in /var/log/syslog when the PCI latency was too low. There were also acoustic and image interferences when the PCI latency was too high. The current PCI latency can be shown via command "lspci -v". Good results were achieved with a decimal PCI latency value around 144 (90 hex) with the mentioned hardware configuration (see manual page of setpci, example: setpci -v -s 03:06.0 latency_timer=96 ). Nevertheless, the appropriate value depends on the specific hardware configuration. Play around with the value and restart DVB-C playback. Otherwise, you can try to swap PCI cards or a different motherboard with a different chipset.Media:Example.ogg
I'd rather see that information split and located on the device specific page TechnoTrend C-1501 and the FAQ & Troubleshooting (where it seems you already added it.) --Hlangos 17:48, 5 May 2009 (CEST)

Thanks for the comment. I agree with you. --Bear97 03:21, 6 May 2009 (CEST)
