I've tried searching Google but can't seem to find anything with an answer. Last night I was watching my brand new TiVo Premiere XL when all of a sudden the THX screen came up in what seemed like a crash. Since then it kicked me into the SDUI and I cant get back into HDUI menus. I checked to make sure there was a broadband connection, I reconnected to the TiVo service multiple times, switched inputs from Component to HDMI and also tried playing around with the quality settings, 480p,720p,1080i,etc. I've also restarted it and pulled the power cable out. Interestingly enough there is no option in Settings -> Settings -> Displays -> for changing the SDUI back to the HDUI (which I had to change to HDUI the very first time I opened the box.) Does anyone have any ideas how to fix it? TiVo's forums dont seem to be of much help. Thanks for any and all help EDIT: FIXED!!!! After wasting 6 phone calls with TiVo technical support (Who is the worst ever BTW) didn't do the trick. I figured it out. You need to go to Settings -> Settings -> Network and Phone -> Change Network Settings -> Get automatically from a DHCP server. As soon as you do that, go back into Settings -> Display and the option to change to HDUI has returned!!!
