[won't see them until October sometime, I know]

Can I expect the quality I will get when they start broadcasting on D*, as I now get from OTA?

I ask because all the locals have at least 2 subchannels (except FOX & WB - are both on same channel until equipment for main WB channel is ready; FOX-HD is 18-1 and WB-SD is 18-2), and during high action and/or fast camera pans (aka football/sports), the picture breaks up into nasty pixellation; especially on the CBS & NBC affiliates.

Will the quality from the D* version of the HD locals be the same as the OTA, or will the lack of bandwidth not be as noticeable since D* will be broadcasting in MPEG4?

DirecTV's quality will be "no better than" what you get OTA (unless you suffer from being too far away from your tower and often get pixilation due to loss of OTA signal).

Garbage In = Garbage Out.

In most cities, DirecTV aquires the OTA signals the same way you do, with an OTA antenna mounted on some local building they use to aquire, encode, encrypt, and uplink each station to the DirecTV satellites.

Some cities use fiber-optic lines from each station instead of OTA antenna, but I believe those are few and far between.

Only way your locals will improve is if your locals stop multicasting and dedicate more bandwidth to their primary station.

I figured as much, but wanted to be sure. Thanks for the info.

Oh well, at least I'll save space on the DVR when recording (whenever they go live on D*).
