Hey all, I have an HDVR2 that reboots on a nearly daily basis. I figured that this was likely the HD, and since I wanted more capacity anyway, I replaced it with a 5400 RPM 160GB drive I had sitting around. The drive seems to work fine, but its still rebooting about five to six times per week. I read the thread about IR interference problems. That is very unlikely in my situation, as I use the RF remote extender and have my tivo locked in a cabinet. Is there anything else I should try with this before just giving up and ordering an R10 while I still can?
