Matt, I look forward to reading it!
I have a quad core AMD with 8G of RAM with 4 tuners and an X Box upstairs that works great. I watch my shows
downstairs while my wife watches hers upstairs on the X Box. I haven't tried watching a movie that I have on my
HTPC to my X Box yet but I am sure I will be able to.
The thing that really made it work well without the lag from one to the other is using a Netgear Powerline. I don't
have dedicated Cat5 but I get great transmission speeds over the Powerline.
I am going to try streaming a movie from my HTPC to my X Box and will let you know it works out.
My difficulty is a main use is for TV series in the bedroom, and I like to watch their special features and some commentaries. HTPCs don't easily support this; everything is built around the use case of only watching the main feature transcoded to a low to medium bitrate MKV.
I see how to build a great whole house DVR; or a movie-room media center for full-disc blu-ray quality; or a whole-house media center for ripped quality main features. But doing all three is...impossible?
If I had time, there are enthusiasts in the NoVA area I could connect with and get demos from, to understand better. But I haven't done that yet
