Cheers guys,

I got it working this morning, I still have no idea what the problem was though....

Basically it seems to me that Maya doesn't like the output from AE, I changed the file sequence title to be MonitorScreen####.jpg (without the underscore) and Maya still wasn't happy about it.

In desperation I took the sequence rendered from AE and loaded it as a background in Particle Illusion and got it to spit out a new .JPG sequence with exactly the same titles on each frame and it works..... go figure!

I'm not sure what the problem was but I'm happy that it works now, hopefully I'll not have the same problem again in future projects!!

All the best,

Mat.
