Hi My patch has helped for Terratec Cinergy C HD card stability problems. Maybe somebody of you want to try or look at it? With Terratec card there were small dropouts while saving data to disk. My patch fixed them (Jouni said so). He didn't have any reboots or something, just small dropouts. I suspect that the problem that my patch fixes is that the DMA transfer from DVB to memory broke video/audio stream somehow. Maybe if you have small dropouts (corrupted packets) in original data while feeding CAM, you will have large dropouts after decrypting has been done? Here is the patch: http://linuxtv.org/pipermail/linux-dvb/2008-July/027226.html I don't have CAM module to test Anssi your case.
