I'm not sure if the full F208 firmware release notes from Dish have ever been posted on this thread so I figured I would post them for anyone interested. I obtained these from Dish in July 2009 when F208 was released and I just came across them in a file folder on my computer. I am posting exactly what I received from Dish via email:
F208 Release Notes
The following issues have been addressed and are fixed in this release:
Stop PSIP time sources adjusting time when TVGOS time has been acquired. This is the behavior where the time is seen to jump back and forth when TVGOS is the time source.
Improved handling for inaccurate PSIP time sources, using a weighted mean calculation to select the correct time. Also added guards to handle daylight savings transitions being signalled incorrectly.
Initial time is now acquired from all available PSIP time sources during installation. Once (if) TVGOS time is acquired, this will be used as the time source.
Added secondary splash screen to notify user that unit is Entering Standby. This avoids the confusion for some after powering up a unit that was in standby before power cycling, this screen only appears in this situation.
Improved USB support - should now support all removable USB sticks.
Daily Schedule now lists repeating events correctly when the event name changes (Dynamically picks the event name for that day rather than copies the initial timer name)
Failed recordings now get reported correctly (with reason) rather than being reported as complete.
Removed a blank screen instance after stopping recording - only occurred when 2 Record Entire Event recordings were in progress.
Correctly display start time, end time and duration for Record Entire Event recordings in menus.
Removed long delay in audio synchronization after trick modes and pause.
In the Guide, the long No Information periods have been segmented into individual 1 hour periods, allowing recordings to be easily scheduled for times where program information does not yet exist.
Fixed an issue where corrupt timers were stopping the unit initializing. This should avoid the situation where the unit stops on the Loading Please Wait splash screen.
Added option to toggle the tracker bar off/on (using the CANCEL key) when using trick modes, or paused.
Added page forward/back in Program Guide using FWD and BACK keys.
30sec skip occasionally jumps to end of program (was fixed in F207).
