With the release of Media Center V4, SageTV has added over-the-air (OTA) HD support. QAM is not supported, though BeyondTV also lacks that functionality in their upcoming v4 offering. Fully integrated European and Canadian guide data has been added to the upgrade, along with additional media and playlist support.
SageTV says: With the addition of HDTV recording and programming guide support, SageTV Media Center now enables Windows users to record a single show or whole season of their favorite standard and/or high-definition television programs on PCs equipped with the appropriate tuner cards. Users can also pause, rewind and fast-forward live or recorded cable, satellite or antenna TV shows, and record multiple shows simultaneously because of the application’s multiple tuner support. HD and standard definition programs can also be streamed to any PC on the network using SageTV Client, and to any TV in the house with the SageTV Media Extender scheduled for release by the end of the year.
