2nd tv tuner

Question

I've tried all the drivers mentioned in this thread, along with the newest one for MCE 2005 from Hauppauge's website too. Bruce, did your upgrade run smoothly when you put the CD in or did you receive the message that your system is not eligible for this upgrade?  I received that message and then used the work-around to install MCE 2005 and am wondering if this is somehow related.
