I would get the JP1 modified URC-6131, from Rob, check over at the JP1 Forum. First try the built-in codes:

Rca Tv-TV0047

Sony Stereo- AUD0158, only after you change the receiver to AV1 mode, see this thread.

Dish receiver- SAT0755, only if its set to address 1.

Apex DVD, there are 8 apex dvd codes in the 6131.
