I am afraid that just because Intel tried and failed does not mean
that we can't do it. Too many open questions.

Is the programmer or team competent? There is a huge difference 
between someone working 9 and 5 and a nearly obsessed programmer
or hightly motivated programmer tackling the problem.

Which platform where they using?

Did they use directdraw ? (assuming that they used win95 or winnt)

What resolution , color depth and bitrate where they using?

The list goes on and on...

At the very least is worth investing the possibility of 
decoding mpeg2.
