If you load ivtv driver it's going to create /dev/video0

root at mythtv:/etc/modprobe.d# ls  -l /dev/dvb/adapter0/

Exactly as it should be.

Also, in mythtv-setup, do I just create a DVB tuner only?  Or do I

There are planty of rousources out there that describe this. I'd
suggest browsing mythtv wiki site.
The first thing I would suggest is try mythtv itself. Go to mythtv-setup,
configure your input (DVB for  HD3000, your source and go to channel setup.

You can scan for channels and if you have any it's going to find them. Then
go back and configure PVR240 (MPEG2 source). You don't have to scan for
channels for
250 since frequencies are well known and will come from zap2it (in US).

Good luck.
