Premire XL only displays SD menus

I have a PREMIERE XL that is missing the ability to switch to HD menus. I noticed this a couple of weeks ago when a notice came through that effect impediately the Premiere will not be able to access Amazon instant videos. I've call Tivo and they are stumped. I've ordered a new drive and that didn't fix it.



Premiere XL

20.4.1-01-2-748

CableCard installed



I'm at a loss. Does anyone else have this issue?



Thank you,



Cris
