Quicktime

Ive just tried quicktime alternative and the medialook plugin but tty still says

00:01:10 ERR : The operation cannot be performed because the pins are not connected.
00:01:10 ERR : One of the parameters is invalid.

Any Ideas of what to try?

Did you try with other betas and/or other versions of quicktime alt?

Tried betas to 14, but not earlier qt. I have had other issues with codecs not registring on this machine despite it being a recent installation os xp, I wonder if it a deeper os issue…
