I have been having the same problem –
I fear the problem here may stem from mixed formats. I have HD footage and SD footage…
When I author a disk in DVDSP I am prompted to make an HD disk.
It plays fine on any I mac, but not on the old E mac, not on psp2 and not, apparently, anywhere else.
The PS2 prompts me to insert a psp2 formated disk, and my E mac doesn’t even recognize that there is a disk present.
Any thoughts would be much appreciated.
Thanks
