Is there any single chip MPEG decoders to NTSC? Can this be done is sofware
and what MIPS might be required?

Your request is confusing. Do you want to know about MPEG Decoders which
convert Analogue Signals (NTSC, PAL, SECAM et al) to a MPEG Digital Format
(1,2,3....) and if so which Analogue and Digital formats. Or do you want to
know about a MPEG Encoder which converts a MPEG digital format to an
Analogue format signal ?
