Umm. CD-I _is_ also a base hardware specification. What you're wanting is roughly the equivalent of asking an Atari ST to emulate all Amiga graphic capabilities, and at something approaching decent speed. And in many ways, the same would apply if you asked CD-I to emulate an CDTV. They're just too different, audio/graphics-wise, for realtime conversions. Actually, the subject of a more machine-independent (eg: CDROM-XA) disc was something I really wanted to get into a few months back during the "CD-I/CDTV Wars" here. But no one would let us get that far along . I do want to thank you for a perfect opening question tho. It _was_ very tempting to ask you how a CDTV player could possibly emulate even a simple CD-I case of a 100-color animation overlaid on a 170,000 color photograph, with hardware transparency effects. Ooops. Sorry! Like Dr Strangelove, I just couldn't help it :-) :-) best - kevin
