I haven't noticed programming advertised as 5.1 not being such when sent to my receiver.
I have not had that happen using a Colossus with Directv. It switches fine and records the program in 5.1 if available even if the intro was in 2.0. I only use Showbiz. If you're using WinTV, maybe that's the difference.
However I have noticed, contrary to your last sentence, that MANY movies which show the "Dolby Digital 5.1 Where Available" line on the intro are NOT available in 5.1 on Directv and are only transmitted with the 2.0 soundtrack. I often go and check and see what the Directv feed is to confirm this. It seems to be a shortcut by some stations often including the secondary HBO channels, for example, and the Sony movies channel. HDNET Movies, on the other hand, always transmits the 5.1 channel.
I've become acutely aware of this since getting my Colossus. It's really annoying that they would transmit an HD movie and NOT send the 5.1 soundtrack along with it.
