I found the answer to what was ailing my DTiVo on, off all places, TiVoCommunity...
My DSR6k DTiVo doesn't like my cheap IRD-powered multiswitch. I have both of the lines of off the LNB connected directly to the DTiVo and apparently all is good now. Several posts on TC dealing with this subject recommend an externally-powered multiswitch for use with DTiVo's.
I'm glad the fix was simple - my next "plan of attack" was to start troubleshooting the power supply... :-0
Thanks for replies!
UPDATE: Well, I spoke too soon... Pixelation is still there, but 95% less than before. Finally got a pixelation-free recording, too.
