[mythtv-users] Building a MythTV system to interface to the DirecTV H20 Receiver

Is it possible to do a HDMI to DVI conversion from the H20 box and capture the DVI input on the MythTV system?
I know this is a ton of data, but has anyone seen a DVI capture and hardware MPEG2 capture card?
I have seen the simple HDMI to DVI coverter plugs but I have not seen Linux based DVI capture cards....

I am building a "from scratch" system to record content from a DirecTV H20 receiver.
Can anyone give me a breakdown on what card (or cards) I should be using to connect the H20 to the MythTV box?
The back of the H20 has USB, S-Video Out, Component Out, Video Out, Audio Out, Digital Audio Out, HDMI Out, Phone Jack, and RF Remote Antenna.
I guess my first question is can I record HDTV content with this equipment?

Essentially no. You would need an encoder capable of HD, and AFAIK there are no consumer level devices available to do that.

Lucent does make such a unit, but I believe the starting price is around $30,000.

If I'm wrong and such a device has come onto the market at an affordable price I'd love to know :-)

I thought that some DirecTV receivers had a Firewire output that could give you access to the decrypted mpeg stream, but I'm not sure about that, and I've never heard of such being available over a USB connection.

You can record SD, the best method would be to connect the S-Video output to the similar input of a PVR card.
