You can also choose the HD channel from the list before you tell it to record. Like if you search for movies (and don't check the HD only box) and find one you want to record - see if it's in HD before selecting record. I think the default is the lowest channel number and may be the SD channel even if there is a HD channel available.Nevermind! I figured it out. Theres a little box to check HD content only. Then record.
