So far I've found around 30 channels broadcasting in DD 2.0.
Wondering this myself. Haven't noticed the audio bit. And the on-screen guide info doesn't show the DolbyDigital icon on 2-99 channels that I've noticed (generally the sign that a Comcast signal is digital).
Did notice not long ago that KVPT 18 shows up on both is old analog channel (ch. 8) as well as on ch. 90 (still in the analog domain, but the audio level is different--louder).
Perhaps some unannounced ADS is happening? I do recall that when HBO was still available on the 2-99 tier, the audio would change to DolbyDigital (sometimes even 5.1), just like it's SD digital counterpart in the 500s
richeydog, which channels have you found this on?
EDIT: OK...went home for lunch today and checked on the 2-99 situation. Looks like ALL channels (or at least the several I checked) are coming into the DVR as "digital". Youcan confirm this on your Comcast/Moto HDDVRs and HD cable boxes 2 ways:

Analog-Digital Simulcasting (ADS) is used by the DVR in local cable markets where ADS is available. The DCT3412, and the tiny non-DVR DCT700, having only digital tuners, always employ ADS. The DCT6208. along with the DCT64XX (all phases), and non DVR DCT models 5100, 6200 1100/1200, 22XX, and 25XX have analogue and digital tuners. In an ADS market, those models will default to their digital tuners, as ADS overrides their analogue tuners completely. Refer to the article on ADS for more information on how the technology is used in cable systems.
Method 1:
Dolby Digital logo with "double-D" symbolTune to a single-digit channel (ex: Ch. 9). These "basic cable" channels would normally be received as analog without ADS.
Press the INFO button. If the Dolby Digital double-D symbol is displayed, the channel is digital, and you have ADS.
Note: The Dolby Digital symbol may not show up on the second tuner. Use the tuner swap button to switch to Tuner 1 to check for the double-D symbol on a "basic cable" channel.
Method 2:
Tune to a single-digit channel (ex: Ch. 9). These "basic cable" channels would normally be received as analog without ADS.
Press CABLE then POWER to shut off the box.
Immediately press OK/SELECT to enter the Diagnostic Main Menu.
Press DOWN ARROW to "d06 CURRENT CHANNEL STATUS" and press OK/SELECT.
If the "Type" is "ANALOG", you do not have ADS.
If the "Type" is "DIGITAL", you may have ADS (this tuner may be tuned to a digital channel that wouldn't use ADS, check the other tuner in the next step to see if it is tuned to an analog channel).
Press DOWN ARROW to scroll to the second page showing details for Tuner 2.
If the "Type" is "ANALOG", you do not have ADS.
If the "Type" is "DIGITAL", and the "Type" of Tuner 1 was also "DIGITAL", you have ADS.
Press OK/SELECT then POWER to exit the Diagnostic Menu. The box will now be off.
Confirmed with both methods that all the 2-99 channels I checked (2, 3, 4, 6, 7, 20, 21, 31, 32, 99) are registering as DIGITAL both with the DolbyDigital logo on the info display as well the Diagnostics Main Menu.
Guess we Comcast Fresno folks are 100% digital now.
Ball is your court, Comcast. With the supposed bandwith savings of all-digital, better start filling up the availablespace with new HD channels! (and not just OnDemand selections).
What I wonder is whether those who get basic cable w/o a box are still geting analog signals and does this still suck bandwith?
