After brutforcing rv20 Linux RealPlayer decoder, I found :
20 10 0 0 -> 20 19 FF FF (Futurama\ 305\ Amazon\ Women\ in\ the\ mood.rm 
0x155)
s->low_delay=1;
20 20 0 2 -> 20 2F FF FF (Video-Galileo-AVC-2003-182_1mb_.rm 0x1a9)
s->low_delay=0;
s->avctx->has_b_frames=1;

I didn't find which have 0x20001000 as sub_id, but if I use this id on 
another rv20 stream the decoder refuse it. I have the same problem for 
sub_id starting with 0x30.

As there no rv10 realplayer decoder in mplayer, I can't test for rv10.

I will make a patch for this 2 type.
