How many streams can be viewed from one box/ I suspect it is only ONE.
You do not need a decoder for the PVR, as you only need to store the 
compressed IP packets - decoding only is necessary when you want to 
view the content. You should be able to find a SINGLE decode design 
that can support all of the codecs that you may use. Since you are 
just starting the system, an H.264 decoder can do the job - just 
choose the level of performance you want to support (SD or SD & HD). 
IF you also want to decode MPEG-2, there is a good chance that the 
commercial decoder chips will do that too (but the royalties will be 
higher).
