Re: [HDTV-in-SFbay] Re: Audio dropouts on various HD broadcasts on DirecTV HR20
- I experienced exactly the same issues you describe with Heroes and
Leno last week.
The OTA version of Heroes on my HR10-250 was clear as a bell but the
MPEG4/HR20 version was horrible. The repeat of The Black Donnellys on
Thursday on KNTV seemed a little better but not great.
I didn't watch any of these shows live so don't know if it's the DVR,
the satellite signal, the latest software release or what.

- I suppose it could, but in most all cases, the PQ from Comcast is as
good as it gets other than OTA. If there's a problem such as you
mention, my guess would be there is a signal/connection problem. To
the best of my knowledge, Comcast sends the same signal to Cloverdale
as it sends to Morgan Hill.
When you say "horrible", what are the characteristics that make it
horrible? Has Comcast been contacted to fix the problem(s)?
