Hi Doctor,
Yes, I was able to manually install 7.11. It had other VisionTek cards listed in the driver installation, but it did not list the 2600 VisionTek card specifically, so I selected the ATI card in the driver list. Everything worked the same as when I had installed the driver supplied by VisionTek, i.e. the same problems existed with Theater View.
Well, after spending so much time trying to make this card work, my wife was ready to kill me since I seemed to have forgot I had two children that needed their dad's attention...so I ran down to CC, bought the PNY Nvidia GeForce 7600 GS with 512MB DDR2 for $80, yanked out the VisionTek drivers and card, installed the Nvidia, and...everything is working great! The 7600 GS is not an HD card, but that was only for future use on my computer. I just got back from returning the VisionTek to BB for a full refund.
I am happy, my wife is happy, my kids are happy, and my MC12 is happy. We are all happy!
Interestingly, ATI promoted Earthsim with their card, which I installed...it is pretty cool...but with the ATI card there were a lot of artifacts in the earth images...yet Earthsim looks great with no image problems using the Nvidia card.
I appreciate everyone's help, but am glad it is over. Now I am off to play with my kids.
Best Regards!
