Thanks to the contributors for all the time and effort.
this might sem like a stupid thing to try, but i've had similar kinds of failures trying to implement firmware on a couple of routers...
the OS on your PC MIGHT be the issue, as well as the software you are using to burn the CD.
if you have a machine with Win XP, try using that machine to burn your upgrade disc.
if you are using the Windows ' Built In ' support for burning discs, don't....
if you don't have either of the above, it might be helpful for someone to burn an upgrade CD ( who has been successful ) and have them ship it off to you to in order to eliminate non-dvr issues that may be impeding your success.
later OS versions ( beyond XP ) have various anomolies associated with burning discs. for all i know, something as silly as dealing with DRM in either the OS disc support or in seemingly ' unrelated ' software ( such as win media player, etc ) may be doing something to the discs that the DVR hiccups on, eg, it might be tripping over some sort of DRM or CP issue and getting confused.
i have only done upgrades on 3576 machines so far, but unless there's some wierd anomoly with your specific machine, i really don't think you should be experiencing the kind of difficulty that you are.
since, with multi-files in a test, your DVR at least asks for a selection, this means that the DVR is indeed reading the disc ok to begin with..
the fact that the drawer opens after a period of time would indicate that the DVR may not be finding some obscure item, such as an EOF flag or marker in the image itself. indeed, the burn procedure ( whatever is being used ), may have a bug-a-boo in it that does something like ' not write the last bit, or sector ', and the DVR reacts by thinking it needs ' the rest ' of the .mot file or some such thing...
just a shot in the dark...
