    I'm in the same area a Barrysb and 4.03 also cleared up my drop-out issues.

    BUT for some reason, my OTA audio levels seem to be much lower that the same Chan received via sat.

    (Note: This audio issue is only found when using HDMI. Audio levels are equal when Switching between SAT and OTA while on composite output.)

    I've always seen OTA vs satellite volume differences at times. I'd guess this is introduced by E*'s uplink processing. Used to see it with D*, also. It's interesting to see the video delay between OTA and satellite; they must be doing a lot of something to the feed.

    The delay is induced in the MPEG encoding process at the uplink and the addition of 44K to 88K miles of signal travel to it to get the uplink and then back to you (including the trip or two to space )

    This is wandering OT (quite) a bit, but how does the uplink center get the video? I just assumed it would already be MPEG-2 encoded, since anything that's transmitted via ATSC is encoded. Even for the NTSC stuff, I'd think it would already be digitized and encoded when E* got it.

    Note that I'm not disagreeing with you, clearly there is processing happening, since the delay caused by the distance only amounts to 250msec per round-trip. Just curious, that's all.

    My OTA dropouts have once again increased. After about 2 weeks of Fox being one of my most stable stations (99% with no dropouts)I can hardly see any channel now. The only difference is the foliage on the trees. I can't believe that the digital signal is this dang finicky. One thing that I have noticed... If I bring up the guide and just let it sit there for a moment it seems to stabilize my signal somewhat. I have seen a channel go from totally useless to being able to actually watch with few dropouts.Once the picture has stabilized in the guide window I just escape out of the guide. I can't believe that would have any effect but it sure seems to help.

    The trees won't have that effect on OTA reception like they do with SAT reception.
