Audio problems with HD

I seem to be having some problems with the audio on the HD channels. All of the regular channels are fine but the HD channels the audio is off with the picture. It's like watching a kung-fu movie. It only does it on the HD channels. My over the air hd channels are fine also. Is this a glitch or what?
It's a common problem with the HD locals - there are many potential reasons most of which you can't fix. Some A/V receivers have a "sync adjust" control which allows you to correct for this, and you can buy add-on boxes also. And the next generation of TVs and A/V receivers using a full implementation of HDMI 1.3 will allow sync adjustment.
Clearing out the internal buffers in the HR20 can also help. Do a "restart recorder" thru the menu.....

I tried resetting it with no luck. All the standard channels seem fine. I noticed it the other night on TNT HD and ESPN HD. My locals and standard channels seem ok.
This has been an interesting problem, in that there are several potential sources for the problem:
1. Many HD setups have it, with no HR20 involved. It is frequently seen with DVD players.
2. Some are associated with specific channels, like ESPN-HD, which is one of the worst offenders.
3. Some are the result of the HR20 itself and are temporary...they can be fixed by changing channels, etc.
4. Some appear to originate at D*, and will affect both HD and SD channels.
So, for any given instance it can be the program provider (ESPN-HD), the home theater setup itself, or the HR20 "gumming up" a bit.
I don't see much of it any longer....but I do still see it on ESPN-HD, and very occasionally on another HD channel. I have seen it OTA-HD on my TV, without the HR20 involved at all.
Really, there are things about HD television viewing that are just not ready for prime time yet. It starts at the studio and plays out right into our own equipment.
Since I went to an HDMI switching and upconverting home theater amp, I have seen a lot less of it than I used to. It's still there periodically.
The only "current" and "ultimate" solution is an external digital delay box like the Felston. This comes up over and over and over again, because there is NOT one single cure for all the possible sources....except something like the Felston, which makes up for a multitude of HD audio delay sins.
Short of that, get used to it, until HDTV matures a bit.

I was also getting heavy pixelation similar to rain fade which would indicate a weak signal to me.
It appears to be better today, but I only had a few minutes to check it.
I'm still only getting 72-79% on 110 while 119 and 101 are running at 90-94%.
