Hi,
I now got video on my PVR 150 MCE NTSC with tuner type 47. It isn't
clear image but there is color video. My previous post doesn't seem to
get posted due to patch > 50KB. Here is the change that I added to make
it work. I applied all the patches suggested in the previous email of
this thread. Then changed the file cx25840-driver.c for "case
CX25840_TUNER:" below after reading the cx25840 data sheet. Later, I
might try to see if I can get a smaller patch.
Here are the changes:
1. Kernel 2.6.11-rc4
2. latest v4l
3. amd64 patch
4. change in cx25840-driver as below
case CX25840_TUNER: {
