 I hear you, I'm sure we all do the same thing, especially when on multiple
lists.

I have just the one HDPVR, and even though it is just a loaner for now, it
has been pressed into production. (Implicit approval from the significant
other, if nothing else.) I do have access in between recordings/viewings if
there is anything you would like tested.

For the record, my setup is Fedora 15 with updates
Was using ATrpm builds, but I had to rebuild Myth rpms from git source a
couple days ago to get H.264 support capture support.

Let me know if you need anything else, thanks in advance.
