Same release I started with. I've since added a PVR-150 as a second
tuner and have 350gb of shows on disk. I had to upgrade to ivtv 3.6y
to get the 150 working but the 350 worked fine with Knoppmyth
originally I assume you followed this?

You don't need to modify the SQL db. There is a channel editor that
will let you make the settings. Since I was able to get my listings
online, I didn't have to do any of that and it worked.

Your 350 is Pal I assume? I can share with you my 2.0 working ivtv

root at mythtvbox:/etc/mythtv/modules# cat ivtv.350only
alias char-major-81 videodev
alias char-major-61 lirc_i2c
#options ivtv debug=1
#options tuner type=2
options msp3400 once=1 simple=1
install ivtv /sbin/modprobe tuner; /sbin/modprobe msp3400;
/sbin/modprobe saa7115;  /sbin/modprobe --ignore-install ivtv;
/sbin/modprobe ivtv-fb; /sbin/modprobe lirc_i2c
remove ivtv /sbin/modprobe -r --ignore-remove ivtv && /sbin/modprobe
-r saa7115 && /sbin/modprobe -r msp3400 && /sbin/modprobe -r tuner &&
/sbin/modprobe -r ivtv-fb && /sbin/modprobe -r lirc_i2c

I really think your problem probably lies in your input settings for
your source, your cable. I don't think you have the channel
frequencies set properly and so, while it works, it's not tuned to
anything. Maybe someone successful in Sweden can chime in with at
least one known good cable frequency?

hope this helps some.
