Thanks for all the comments, but I think I'm staying away from Costco scans in the future.
I just had the DVD that none of my computers could open re-scanned at Costco. The other four DVD had photos scanned at ~6mp, this one came back with photos scanned to ~3mp, with the same problems that I noticed before concerning contrast, color, detail, etc.
Below is one example. Since I don't have the film copy side by side here I don't really expect anyone to really see what I'm talking about, but basically there's a loss of color, detail, and most problematic of all is that the photos come out way too contrasty and blown-out.
I definitely suggest those that plan to have their films scanned to DVDs at Costco double check to make sure that the right roll was scanned, and try the DVD at the printing station just to make sure it works. I live a good 10 miles away from Costco, add in the taffic three trips to their stores due to their mistakes just isn't worth it for me.
