The compression capabilities of my posterior notwithstanding, Ken seems to be the only one here who is actually "helping".
I am lucky enough to have a periodic allocation of funds from my employer to spend on things like computer equipment. So, my question really relates to how I can best leverage that resource rather than how I can best acquire BD capabilities.
I did quite a bit of reading at AVS, and it appears that you can't get the new audio formats from a PC yet. However, since my receiver doesn't have HDMI switching, the point is moot at the moment. I'd be content to build to full capability while enjoying the 1080p picture and DD EX.
It's all part of my master plan. Bwahahahahaha!!
