RE: Pioneer 810h, 7.2, replacing/using larger hard drive. I originally had 5.x on a 200GB in my Pioneer. Upon upgrading to 7.2, I had nothing but freezing issues all over the place (oh, my TSN starts with 275). Tivo pointed the finger and Pioneer and they pointed back saying that there might be something wrong with the HD. I took the WD 200GB out, performed a extensive test (with their software), which revealed no problems. I put my original 80gb in the unit, let it upgrade to 7.2, and no matter which iso/software/commands I use, I have problem - no background (transparen screens), warm reboots while switching between any screen, even when attempting to view Information or download and organize programming information. Something is diffferent in 7.2 - partition layout, checking of hard drives or something else, but I am really frustrated. I'm glad I purchased a Best Buy Extended warranty, because I've also had problems burning to KNOWN GOOD DVD-R media. I'm getting ready to either use Macintosh software to accomplish the same goal, or return the unit for a DVR and get DISH (I can't stand DirecTV).
