Vista works quite well with HDTV. (as on the HP m7760n desktop)
There is one suggestion -- Vista's MediaCenter won't let you specify
"Record in HDTV if possible". It only lets you set "Any Channel" or
"Only this Channel". There may be helpful if users can choose "HDTV
if possible" (for quality) or "SDTV if possible" (to save disk space)
There are Vista specific newsgroups:
microsoft.public.windows.vista.administration_accounts_password
microsoft.public.windows.vista.file_management
microsoft.public.windows.vista.games
microsoft.public.windows.vista.general
microsoft.public.windows.vista.hardware_devices
microsoft.public.windows.vista.installation_setup
microsoft.public.windows.vista.mail
microsoft.public.windows.vista.music_pictures_video
microsoft.public.windows.vista.networking_sharing
microsoft.public.windows.vista.performance_maintenance
microsoft.public.windows.vista.print_fax_scan
microsoft.public.windows.vista.security
Several other MS newsgroups are independent of the underlying OS, so, for
example, IE7 issues whether Vista or XP go to the internet explorer
newsgroup. microsoft.public.internetexplorer.general
For mediaplayer issues and mediacenter there are these newsgroups:
microsoft.public.multimedia.windows.mediaplayer
microsoft.public.windows.mediacenter
microsoft.public.windows.mediacenter.hometheaterpc
microsoft.public.windows.mediacenter.portable
