I bought a HD-PVR recently. My summary is: It works great for minutes
at a time. I have yet to get one successful capture under Myth.
I've done a lot of testing (some of which was reported previously on
this list) using three different computers, have used both Windows and
Linux, have used multiple versions of the firmware, and bought an add-in
USB card to try something other than motherboard USB ports. The HD-PVR
only worked consistently under Windows. Under Linux, whether using Myth
or doing direct captures from the device, it is far from reliable using
all of the same cabling that works with Windows (which rules out
overheating, power supply, cabling, etc.)
I'm leaning toward the hypothesis that the USB implementation of the
HD-PVR has an issue, possibly some type of timing issue that leads to
deadlocks. I understand that many people do have them working, but you
can see the number of people who have had problems and had to try
different cables or USB ports, etc. Also, as you note, there is someone
who produced a software controlled power switch to reset the HD-PVR.
All of this should serve as a warning that the HD-PVR is a bit of a crap
shoot. You may get a working capture device or you may get a $200
paperweight.
