I'm glad to see this.  I was beginning to wonder if /anyone/ had a 292e 
working with HD in Myth without a patch.

...and I think it might be worth checking that you really /are/ using 
the device that you intend to use.  At present a reboot still puts my 
tuners in quasi-random order and I have to unplug/replug my usb device, 
perhaps several times, to make sure it's properly initialised.  dmesg | 
grep adapter can be useful.

...and testing with vlc might still be useful too, although clearly it 
won't help in sorting out anything that's Myth-specific.

Good luck.
