Thank you.

[..snip..]

Did a `hg clone http://linuxtv.org/hg/~mrechberger/v4l-dvb-kernel' in
v4l-dvd-kernel `make config' patched one file[1] and then did a `make'

v4l$ ls *.ko
compat_ioctl32.ko  ir-common.ko  tuner.ko     v4l1-compat.ko  videodev.ko
em28xx-audio.ko    ovcamchip.ko  tveeprom.ko  v4l2-common.ko  vivi.ko
em28xx.ko          saa7115.ko    tvp5150.ko   video-buf.ko

Wrote a script to fool around with new modules:

<v4lnew.sh>
sudo rmmod em28xx
sudo rmmod videodev
sudo rmmod tuner
sudo rmmod saa7115
sudo rmmod compat_ioctl32
sudo rmmod v4l1_compat
sudo rmmod v4l2_common
sudo rmmod ir_common
sudo rmmod tveeprom

sudo insmod ./compat_ioctl32.ko
sudo insmod ./v4l1-compat.ko
sudo insmod ./v4l2-common.ko
sudo insmod ./videodev.ko
sudo insmod ./ir-common.ko
sudo insmod ./tveeprom.ko
sudo insmod ./em28xx.ko
sudo insmod ./tuner.ko
sudo insmod ./saa7115.ko
</v4lnew.sh>

$ mplayer -vo xv -tv driver=v4l2:freq=559 tv://

Only lists various PAL variants as supported norms, the picture is grainy
and monochrome, picture for the "good" (i.e. real PAL channel) stays okay.
No audio still (for either channel, witnessed by running:
 arecord -D hw:1,0 -f cd | aplay
while mplayer is also running)

<part of mplayer output>
Selected device: Pinnacle PCTV USB 2
 Tuner cap:
 Tuner rxs:
 Capabilites:  video capture  tuner  audio  read/write  streaming
 supported norms: 0 = PAL-BG; 1 = PAL-DK; 2 = PAL-I; 3 = PAL-M;
 inputs: 0 = Television; 1 = Composite1; 2 = S-Video;
</>

Any mistakes in above? Anything else i can/should try?

[1] Patch to make em28xx-input.c compile for this (2.6.20.1) kernel
