I have DirecTv and my capture card is hooked to it.
My card is a Happaugue PVR150
I run my audio through a surround sound receiver and all my movies have 5.1 audio.
My receiver has the decoder built-in
Will this setup work with this software as far as recording off the TV and playing imported movies with 5.1. surround?
Recording - Yes, as long as you use DirecTV's box to tune to channels. You can not tune to Satellite TV using MC and your card.
Not sure about 5.1 surround. I think it will do.
Is there an option to download a TV Guide listing according to your provider so you can easily schedule recordings?
No. You have to schedule a recording manually by specifying a channel and start and stop times.
Lastly, I currently use the IR Blaster that came with my capture card and it automatically changes the DirecTv channel and allows me to do any function within Sage TV using the remote.
I don't really plan on using a mouse and will mainly use the 'Theatre' view as the Windows desktop is very hard to view on my widescreen.
You can use MC's Thearter view.
Is it a major nightmare to get things working?
(some software is easy and just works out of the box and others you have to tweak)
No. If you encounter problems, come here. We will try our best to help you.
Lastly, does this software allow any scaling to hlep fill screen?
(I have not installed software on my HTPC yet, only my desktop which doesn't have a capture card)...
Install and try it!
You have the following display options - Source Aspect Ratio, 4:3, 16:9, ... , ..., Stretch, and Crop. I think the last two are what you ask for.
