i have had the exact same problem and i won't install 805 just cause i don't feel like reconfiguring my entire remote system every time.
there's also this thread
http://forum.bsplayer.org/viewtopic.php?t=3999 that didn't get any response from BSPeter or any other BSP team member and that's a shame cause i'm sure alot of people encounter this issue.
Please let me know how to manually save these settings so I can install 805, and I think you should make sure the next build doesn't erase these settings.
