I understand your frustration. I have a similar set-up (i.e. Comcast clearQAM, etc) and have had several instances of lost guide data. The first was around Thanksgiving and the second was about a month ago.
In both instances, I tried many resets, but never the "full factory restore".
The latest resolution seems to be ideal for me. Apparently, Comcast is passing TVGOS on analog channel 93 (Host ID shows up as 1:93-0 on the 753 menu) and data is filling in nicely. I don't think its coming from an analog TVGOS source as I routinely have "No Listing" show up on Day 8, yet the next day, they fill in with details. With analog TVGOS, those No Listing wouldn't clear up for 3 days (when the orignal Day 8 becomes Day 4).
My theory is that Comcast is converting the digital TVOGS data from CBS 3.1 and putting it on an analog channel.
As and added bonus, all of the extended Basic channels are clearQAM, so I can stop recording the analog channels and save a ton of HDD space.
If I were you, I'd follow frank70's guide to trying to establish a digital host. In the process of doing this (4 day process), the G* test is run. I find that when I run the G* test when tuned to 3.1, the clock gets set properly.
All I can say is keep trying as my guide issues have cleared up. I can't be sure what exactly I did to get it to work, if anything at all. It could be that Comcast fixed it on their end.
For the record, I'm in SE Pennsylvania. Delaware County, PA if you want to call your Comcast office and have them contact my Comcast provider to see if they can replicate it out in the Pacific NW.
