Hmm.  I've been using MythTV with my HVR-1600's since I first got one a
few years ago.  You just set it up as two separate cards: an MPEG
Encoder PVR-xxx like card and a DVB adapter.

This version of MythTV works for me:

$ mythfrontend --version
Please include all output in bug reports.

using_live


The only problem I noticed is that the digital cahnnel scan can bomb-out
near the end.  Apparently mythtv-setup tries to tune to a freq higher
than the demodulator can support and then mythtv-setup crashes when the
error code comes back from the cx18 driver.  The channel scan
information up to that point is still saved however.

Or maybe I misunderstood what you were saying.
