There are really no options for capturing HD from any satellite service.
Depending on your cable company you may have the ability to capture some/all
channels via firewire using a cable box however the satellite boxes do not
have any way to capture HD (This is no accident, they want you to PURCHASE a
hd dvr from them.)

1) Capturing the HDMI output -- obviously HDMI is made to avoid this

2) Capturing the component video output -- but what resolution will a

Only possible at SD resolutions right now.

No cable card support in any PC based capture card. You might be able to
suck the programming from the tivo but not real-time and there may be issues
playing the video in myth.

Is there any good option for me here?

Get cable and a HD stb and hope they have not blocked everything other than
your local channels for firewire capture. Good luck, the choices are not
good these days and the providers are working hard to remove them too.
