Fuzzy Images

I've been following a series of these older questions and haven't yet seen a solution to my problem.

I'm at a new job (new laptop) with new installations of both PPT and SL 2. My previous experience has been very good with importing PPT files into SL and getting good image quality published output using custom optimization as suggested in this thread. However, using every angle and trick I know and have researched to this point, everything in the content frame regardless if it's from PPT or created in SL is unacceptably blurry.

I typically set up for full screen viewing based on the fine detail I need to show - and of course that gives me the worst image - but optimized settings are not really any better. All the player image looks great (menu, frame, player bar etc.) but the content image quality is not good at all.

I've tested "9 ways from Sunday" with out any difference in output.

Note: This ain't my first rodeo but for the first time I'm publishing for the Web rather than for an LMS. Is there that big a difference in quality?

Any advise would be appreciated!
