There are a few issues with the BBC America HD channel that I haven't noticed on any other HD channels (which isn't to say they aren't happening). Firstly, an audio desync. It's short but noticeable. A line of dialogue being delivered a fraction of a second faster than the lips finish moving, things like that. Second, advertisements will play at inappropriate times (in the middle of a scene of TNG, before the "Commercial Break" music sting + fadeout).
You need to contact both DTV and BBC as they are the ones sending the signal to DTV.
