Well, if you'll "promise" to help me getting it to work, I'm willing to buy a
card. Since the drivers doesn't seem to be a problem, getting it to work with
MythTV *shouldn't* be any problem, right? Like, how big is the risk it won't
work at all? Of course you'll get access to the machine if you want to, during
the development. Sadly I'm not much of a coder myself.

Software emulators are availible on Windows, and yes, they can be used in a
"piracy" way. But that's not my intention. An icepick is a very dangerous weapon
in the wrong hands, but does that make it illegal? Everything can be used the

Probably I'll have to do it this way. The Happaugauge/Technotrend cards have
this capability. Will it be possible to determine, without the CAM module, if
the card will be useable at all? (this way I won't have to buy it if everything
goes to hell, hehe)

Okay, just thought you maybe knew anything about it.
Some other questions.
Subtitles are broadcasted seperatly somehow, right? I guess this doesn't work
Does this type of card support PiP without having two cards? I've got a vague
memory of you writing that sometime, pointing out that the only thing stopping
that is that MythTV doesn't know about it. Is that true? Would that also mean
that multiple recordings and watching at the same time would be possible?
Is the onboard MPEG-2 Hardware-Decoder useable in any way?
