Unfortunately almost all inexpensive universal remotes only offer basic functions meaning buttons like "Bass Mode Auto; Dialogue Surround; Virtual SB Advanced" are unlikely to be supported. Even remotes purporting to be replacements (here and here) appear not to offer these options - the reason I usually advise the purchase of a learning remote.

Obviously this latter option is of no use to you, however, I have found this though the price is ridiculous (but, alas, not unusual).

Perhaps a slightly more inexpensive option may be a JP1 remote, but you'll need to talk to 3FG about those, or go here.
