IMHO, the RCU810 is a better remote than the AV2100.
I'm not familiar with Philips SAT dishes, but if it has TiVo built in, did you try the TiVo code (which is VCR/0635 in the RCU810).
Failing that, did you try simply learning from the SAT remote? You can learn about 24 buttons before the memory runs out.
