DVD9 > DVD5 with Pc files?

Hi, i have done the difficult bit of authoring this dvd to fit dvd5 etc, but, i cant seem to do this final bit, which is to add PC Files. I have tried Nero with UDF/ISO and adding it like that - doesnt play in my dvd player (toshiba SD210E) i have also tried Prassi - however, it just burns a disc of 900meg, even though before writing it says it will write 4.3gig. I have tried creating an image with image tools, but it makes an image without the PC Files. i have been trying to get hold of a copy of DVD Motion Pro to make an image, but that is nowhere to be found :( its even more difficult to get than scenarist - which says a lot! i would appreciate any help, thanks :)

what program did you use to reauthor the disc? Enf...

scenarist m8, told it that there were pc files and everything.. aint got a clue what to do now :(

ahh, toshiba dvd player, if possible try a different player, had bad experience with toshiba's and burnt media this week. Enf...
