My 2 month old XL recently started seeing the freeze/reboot issue that a lot of you are experiencing. (Note I am using the SD menus.) For the first 10 weeks or so, it ran without any issues. I forgot that I updated my MediaSmart server to 3.0, and added the TiVo Server add-on around the same time. Are any of you experiencing the freeze/reboot issue NOT using the MediaSmart TiVo app? If not, are you using a TiVo Server?
