Hi Ronald, Highest allowed bitrate leads to 1:2 compression, so for a 768x576 at 2bpp at 25fps (full PAL), that is 768x576x2x25/2 =~ 11 MB/s max (in theory). ok, thanks for clarification. Nevertheless, the linux driver seems to allow a higher bitrate (or lower compression) than the original d

Hi Bernhard, Which CPU do you have ? Do video programms like xawtv work ? Which input do you want to use ? What does really work ? What is the output of lavrec ? Sorry for being unclear: capturing (with lavrec) works perfectly for me, the only thing that bothers me is the limited buffer

Hi, this is probably a FAQ but I looked through the docs and the list archive but didn't find a definite answer. I'm trying to get my miro DC30 to work with the driver included in kernel 2.6.12 (actually it already functions quite well). But it seems that I'm hitting a hardware bug with my zoran
