Take the original remote and goto the big box stores, walk to the DVD aisle and shoot some codes at the toshiba players....

I had to do that with a samsung unit a while back for a cutomer who had a crestron system and WOULD NOT pay for upgrading the programming, since there was a problem with the original company about how old the unit was and if it was under warranty, so they called my company, and that is what I did.

Its pretty ghetto, but it worked!
