I'm pretty sure that Dish owns Slingbox now, and that their newer receivers have slingbox built in. This would solve your issues- you wouldnt need an extra pc, card, software, etc. Just the network connection. I would look in to that. Slingboxes are awesome.
That might be true, too, and a much more elegant solution, let me know ASAP, as I am planning to mail this unit around 2pmish. [edit] Never mind, just going to ship it and let you decide what is best....will hit you with email for paypal once I know what shipping costs. DD
