Could be, is he trying to do video to video then ?
There's a way round that, a little device called a 'Bug Blaster' you put in between the two videos and that rids the macrovision (I used to copy and sell pirated videos years back)
If that's the case, and you/he wants such a device, I think I still have one somewhere you can have, let me know and I'll check to see if I still have it..
