Hi Khephren,
Well, first as mentioned, try to get as much info about your system as possible, RAM, hard drives, all installed cards and daughter boards, and if they work or not :lol:
Minor nitpicking: The PAR is not an MPEG encoder, it uses a variation of JPEG, Motion JPEG, iirc...
I have had to send a pretty nice 4000T (see my sig.) through the mail for repair, obviously, if you can avoid this it would be best. But, that said, I think you may get much more for your picasso 4 w/ SS and FF if you sell it separately via EBay.. maybe even the Warp Engine, too bad it's a 28MHz... but who knows... Amiga hardware can go for crazy prices sometimes...
Just my .02 ...
