Eureka...I have finally found the perfect combination! Thanks for all the help and different opinions. I have been experimenting over the last week with different burners and media. I have burned at speeds ranging from 4x to 48x according to what each burner would allow.
The clear winner so far has been the Pioneer DVR112d or DVR212d depending on whether you have IDE or SATA.
When teamed up with the Taiyo Yuden CDs (The cheapest thermal printable ones with the light blue data surface), it blew my mind how good the results were. By burning at 24x with these CDs, my old Turbo Duo responded to these with the same load times and read quality that I get with my originals. I cannot emphasize enough how great my results were with the Pioneer & Taiyo teamup at 24x. I also tested Verbatim LightScribe CD-Rs (because I also have an HP Writer with that Capability) on the Pioneer, but had to burn them at 10x to get close to the same results.
I have not been able to get good results with TDK, Maxell, or Sony CD-Rs using any burner but the Pioneer and then only at 10x. Once again, my Turbo Duo has much longer load times between levels (especially on Sapphire) and the laser makes a low volume whirring - squealing noise as it reads lower quality discs or burns. On the new Pioneer burner and the Taiyo CD-Rs at 24x, the load times are as perfect as original CDs and there is silence as the Laser reads and plays the game backups. In fact these are the best results I have ever gotten with any burner or Cd combination I have ever used in the last 10 years. I hope this can be of help to someone and once again I really appreciate all of the help and input!
Once again...the best combination of Modern CD Burner and Blank CD-R for Turbo Duo Backups is the Pioneer DVR-212d (if you need an SATA Drive) or Pioneer DVR-112d (for IDE) and the Taiyo Yuden CD-Rs.UPDATE: The newest models are the Pioneer DVR-115d (IDE) and DVR-215d (SATA) I just put the 115 in my office computer and it works just as well as the 112 or 212 for backups. I have not been able to find the 215 stateside yet.
