Hi all,
I got myself a 500-MCE to play with about a week ago and I still haven't
managed to get it to work :-(. It doesn't help that I don't know what the
tuners are (I've seen several posts saying to look under the sticker but I
can't see where exactly). I live in New Zealand (PAL B/G)
The machine is an athlon 2500+, nforce 2, nvidia geforce4, onboard sound, etc.
I started with kernel 2.6.10-rc2 using ivtv-0.3.2e +
cx25840-wm8775-2005-01-03_23.56.03-patch. I finally gave up on this and
upgraded to 2.6.11-mm3 with ivtv-0.3.2i. I had some problem compiling
0.3.2i, I had to copy i2c.h from /usr/include/linux to the ivtv directory
since gcc claimed id wasn't defined. I'm guessing it was
loading /usr/src/linux/include/linux/i2c.h instead, but I don't know why.
Anyway, copying /usr/include was all that was needed to get it to compile.
On the old setup I was able to get /dev/video{0,1,16?} and a couple others
created. However, every attempt to read from these files blocked after
around 650k. E.g. dd if=/dev/video0 of=/tmp/video0.mpg count=1000 would
work, but count=2000 woudln't. The generated mpg was static, with some
larger coloured blocks of static towards the bottom. Occasionally I would
get much less than 650k, but normally I'd get within a few k either side.
On the new setup I get a segfault on the modprobe ivtv. The oops follows:

I wondered if it was a tainting issue so tried the modprobe without X, but got
the same result. Here is the lspci output:

The script I've been trying (downloaded from an earlier post) follows:

echo Loading tveeprom
modprobe tveeprom

echo Loading videodev
modprobe videodev
sleep 1
echo Loading cx25840
modprobe cx25840 i2c_enable=1
#sleep 1
echo Loading tuner # (This is the one supplied in ivtv-0.3.2b, rename the
tuner.ko one in the kernel)
modprobe tuner
sleep 1
echo Loading wm8775
modprobe wm8775
sleep 1
echo Loading ivtv
modprobe ivtv ivtv_std=2,2 tuner=52,52
# also consider tuner 38, or tuner 56, or tuner = 5
# to tweak audio
# ivtvctl -p6 -u1 -d/dev/video0
# ivtvctl -p7 -u1 -d/dev/video0
# ivtvctl -p6 -u1 -d/dev/video0
# also look into adding tda9887
# Example test
# modprobe ivtv ivtv_std=2 ivtv_debug=1 tuner=38
# ivtvctl -u 0xff
# ptune.pl --channel 1 --input /dev/video0 --freqtable pal-newzealand
--tuner-num 0

Any help would be appreciated.
