Hi, M A! you might be better off on the video4linux-list to meet people with such cards.

We have reports that analog sound works connected from J3 on the board. If to CD-in or AUX-in doesn't make a difference, except for the mixer controls. However, cx88-alsa is supported too. > 2) Any way to get better picture ? This card is supposed to have hardware encoding (??) but my cpu usage (1.6Ghz intel with 512 MB RAM) is about 50% when watching live TV. Most of it is from mythbackend. Is it actually using hardware encoding ? Better picture, this goes on since years, but to adjust the minor controls is all. On analog video, which has by far the highest throughput, it depends on formats, size, deinterlacing etc. You have to know what you are doing. The mpeg encoder needs firmware. If you start a simple TV app on /dev/video0 and then "cat /dev/video1 > my_high_load_;).mpg, you should see the difference. The 2.6.18 was a good kernel, but you might consider to come a little bit up, the guys have been working on it. If trying to use the v4l-dvb master mercurial, take Mike's current warnings into account for that tuner. The radio likely doesn't work yet, can't tell for the other analog inputs offhand.
