HDMI Cable Length and 1080p/60 Signal Degradation
One of the annoyances I have been experiencing with my new media system is the fact that "snow" appears on my screen when I select 1080p output for non-1080p sources... such as regular definition DVDs. Please refer to the picture below of the second disc of my brother Bryan's favorite movie, The Fellowship of the Ring:

After some experimentation, some help from my home teacher - Cameron (also a PS3 owner), and some googl'ing I finally figured out that my HDMI cables won't support 1080p/60... which requires about 3Gbit/s of bandwidth. The lack of support is not because of inferior quality of the cables (which work fine when displaying 1080p/24 content), but because of the length of the cables. The cables I bought were 10 feet long which I thought I needed at the time (since the cables must run out from my components through the back of my cabinet, up over the cabinet in the wall's dead space, and then through the wall, and plug into the TV. Well, it turns out that 6 feet of cable will suffice (thanks Cameron for helping me with my cable runs!). Sure enough, a cheap $30 6-foot long HDMI cable (that I bought down at Fred Meyer) solved my "snow" problem.

Anyone need a couple of 10-foot long HDMI cables? $10 and they are yours.
