Hi all, I'm using : - a PCI Avermdia DVB-T 771 card with an Asus Pundit-R. - the DVB drivers from kernel 2.6.13.2. The card seems to be well detected (modprobe mt352, modprobe dvb-bt8xx) : [------------------------------------------------------------------------------------] Sep 25 16:03:20 katagen kernel: bttv: driver version 0.9.16 loaded Sep 25 16:03:20 katagen kernel: bttv: using 8 buffers with 2080k (520 pages) each for capture Sep 25 16:03:20 katagen kernel: bttv: Bt8xx card found (0).

I have to reload the modules to obtain (again) a corrupted image ... The same type of problem is described in an old message http://www.pvrguide.no-ip.com/bbs-old/viewtopic.php?t=26618&postdays=0&postorder=asc&start=0 but don't give any solution. Is this problem related to the hardware, the modules or the kernel version ? Any idea ? Thanks in advance for any help, -- Sylvain Argentieri
