I've been using the same Pace Vegas DVR for about 2 years now and have been waiting and waiting for Comcast to update the firmware to accomplish everything that lindend has indicated were in the new versions. It finally happened, I'm also in the Bay Area like Taed.
The diagnostics dashboard from pressing 'ok' just after 'power' indicates that the SW Version is 10.75. From the Comcast 'Setup' menu and 'Cable Box Setup' the 'Configuration' indicates S/W Ver 75.69, and Firmware 99.98
Unfortunately I am not too happy with some of what has transpired.
First all my DVR series recordings were deleted, not the recorded programs, but the fact that I want new recordings of a specific title saved. The problem is that I did not expect this and for the last week have been manually recording programs because they were not showing up as an 'scheduled recording'. The bad and annoying part is that many of the shows are off for the summer, and so I can't put the series recording back in place until the show is back next fall or even until 2010 for some shows, and I will probably miss an episode or two because I won't be paying attention to when every show returns, or remember the name of every show that had a scheduled recording.
The very big elephant sized problem may be similar to what jctl reported. I do not have a HDTV. Prior to this new firmware, shows that were in widescreen had the traditional letterbox bars. After getting the new firmware the DVR seems to be permanently stuck in zoom mode. I can not get any response when I press the 'HD Zoom' button, and I do not want to be in zoom mode. The DVR display does not even flicker the regular indication that a button was pressed on the remote control. Shows on network TV that were previously widescreen are now zoomed, and have the edges of the frame cut off to fit on my 4:3 tv, and the shows are not as crisp as they previously were. Other shows that were in 4:3 are also being forced zoom so I lose action around all four edges of the screen, and the picture is not as crisp because it is zoomed.
I waited so patiently through Comcast dragging their knuckles on upgrading the firmware to help stabilize this DVR. It was absolutely annoying when the DVR would lock and reboot, and then take 5-10 minutes to reboot and let me regain access to channels and OnDemand. Comcast even sent something to plug the DVR into and then plug this device into the wall. Unfortunately they picked some 1.5" x 3.5" brick that has absolutely no chance of fitting into my powerstrip and so it goes unused.
If this DVR will no longer let the user be in control of the 'HD zoom' button to put it in the proper display format, I suspect that many people will return this device. Watching TV in zoom is not enjoyable except for few seconds at a time trying to read small text or graphics on screen. The director of any show did not frame the shot for only the center of the screen to be displayed and all the edges dropped, and it is not the proper resolution leading to fuzziness.
I know that most of these issues are Comcast being dopes and not properly testing. But why would the firmware eliminate the ability to unzoom??? Especially why would it put me into permanent zoom instead of letting me choose if I have a widescreen or not? Because this DVR does not do HD, I would guess that many people are not using it on widescreen tvs and would prefer to have it in the intended display for a specific show, whether that is wide screen or 4:3 but not zoomed for all shows no matter what, or the option to choose which mode they want it in.
