created a HD3000 card in mythtv-setup and assigned it to bcast. I<br>
created a new Zap2It entry for broadcast TV and assigned this to the <br>

What exactly does "...assigned it to bcast." mean? </div>

We need more
information about your system: Which kernel are you using?
If you are not using the DVB driver for the HD3000, well..., you should
be!</blockquote>

Note that I haven't rebooted when working on this. I just:<br>
/sbin/modprobe cx88-dvb<br>
and the modules load.<br>
However, I just rebooted and I had to manually:<br>
/sbin/modprobe cx88-dvb <br>
to get the modules to load (so that /dev/dvb/adapter0 would be
created.) Don't know why. But, that should be a separate problem,right.<br>

I
would also be interested in the messages from the system log during the
boot-up of your system. Specifically, the messages that show the
HD3000 card being detected are of great interest. <br>
<br>
Another possible area of interest is how the PVR250 is detected and
initialized, but I'm assuming that it continues to work, even with the
HD3000's difficulties. </blockquote>

Yes.<br>

be some conflict between the two cards and/or between the IVTV software

here is (relevant) dmesg at bootup (too long to include all):<br>
