Can someone help me? High Res. PDF's are WAY TOO SMALL

Question

Hi All!
Recently I've switched computers and had to put all of the settings from my previous computer onto my new computer. This has gone well, apart from one problem. I've installed all of the same settings from my previous Distiller onto my new Distiller (same versions - CS3) on my new computer, which should mean that when a postscript runs through Distiller, it makes a low resolution pdf and then a high resolution pdf. The low resolution pdf's work fine, but my issue is with the high resolution pdfs.
The high resolution pdf's my old computer made were about 12MB, but the high resolution pdf's that my new computer make are more like 1.2MB. It doesn't seem to matter what I do, whether I export from InDesign or run it through Distiller, the results are always the same small pdf. Has anyone got any ideas?
Oh, and usually the postscript will be bigger than the end pdf - eg: 6.6MB. If someone could get back to me, it would be greatly appreciated!
Thanks!

Hi Murrayviews
What are you making your pdfs with? I had an opposite problem in that my magazines created in InDesign, when outputted, usually - say 2mb a page suddenly blew out to -say 10mb or more per page. My situation was caused by using my web offset printer's joboptions for Distiller which had changed from "Compression -jpeg auto" to "Compression-zip". An earlier size blow-out was caused by them supplying Creative Suite printer settings which changed the ICC profile from Web coated SWOP to ISO - which caused Photoshop to output immensely huge files (take the 100kb photo file turning into a 1mb file).
Perhaps food for thought - something must have changed to have caused such a drastic result for you.
Good luck with that and sorry not have been more help.
