Sounds to me as though you don't have the channel number set up correctly
in mythsetup. Note that for each channel, the channel number is on the
second page of the setup (I think its the 1st field of the 2nd page) - if
this is blank then you'll never change channel, either internally or
externally (as both methods use the same field for the channel number
info).

You're gonna hate this, but "it just works for me"

That sounds to me like you've got a 0 somewhere there should be a number.

http://criggie.dyndns.org/crap/tvone.jpg Thats my mythtv-setup --> 5.
Channels --> then TV One. Compare and see whats wrong on yours.

Your're right, I've wasted hours on this. The software v4l based cards
always just worked.
I had it working with an old mythconverg database (with the RVR150's),
except it wouldn't upgrade to the lastest schema in 0.19 so I started again.

I'm really starting to feel the heat from the wife, it's part of her
life support system :-P

Looks just like yours, I've even set the frequency ID on the next page.

Funny - I've always had the opposite... I own two simple cards that have
just not worked with myth... a SAA7134 (which is now running as a camera)
and a hauppauge wintv GO card (bt878) which simply will not give sound.

Aye - some myth users suggest you have a separate slave backend for
testing purposes. Not got this myself either.

Kernel 2.6.16.11 and ivtv 0.6.1 I had to do this to get the tuner part
of one of the PVR150s recognised. Its all working now.

There's also a ivtv 0.8 series in svn... but thats getting a little too
risky for my taste.

You did stop and restart the backend processes etc?

It is possible there are some silly records somewhere in the SQL
database... How comfortable are you with sql? Try this:

backend> mysql mythconverg
This runs mysql and conencts to the myth database

mysql> select * from channel;
Shows you all the records in the table named channel. Its quite wide. I
have 12 rows in the table - but only actively use four channels.

These next two lines are the field names, and the TV One record. Compare
with yours and see whats up.

Thanks, I've fixed it now. I ended up trying to reload a backed up old
database that had previously failed to restore into mythtv-0.19 (using
msqldump). With mythtv-svn it loaded fine.
Definitely some issues with upgrading from older database schemas
between the two versions.
So I'm off the hook. :-)
