Thanks, RobertRinehuls. As you suggested, I'm going to contact Hauppauge before I do anything else, and ask them if they can give me assurance that their WinTV 7/driver CD package is compatible with my particular Vista setup. I am assuming there is something in that CD programming which makes TitanTV act as the EPG and program scheduler, and is why I would need to download TitanTV (which is free) to be my EPG. (Am I understanding this right?) If it works, $9.95 for the CD would be a small price to pay to fix such a big mess!
FYI, Hauppauge website http://www.hauppauge.com/site/products/data_hvr1600.html has some information about the WinTV-HVR-1600 tuner, which is the one I have (the one used by MS in those early versions of Vista HP 32-bit with built-in WMC.)
Here's a partial quote from that Hauppauge website:
Notes:
- For Analog TV reception, you need an analog cable TV connection. If you have a digital cable set top box or a satellite box, the WinTV-HVR-1600 can connect via either Composite or S-Video inputs. Channel changing will be done using the IR blaster.
- For ATSC over-the-air digital TV reception, a high gain antenna is recommended. To check the ATSC TV broadcasts in your area, go to TitanTV.com and enter your postal code.
Note: depending on the strength of your antenna, you might not be able to receive all broadcasts list at TitanTV.
- To use the WinTV-HVR-1600 for TV with the Windows Media Center application, a Media Center certified DVD or MPEG-2 software decoder should be standard in your Media Center PC. If you are building a Media Center PC, check Microsoft's web site for a list of Media Center certified DVD decoders. The Windows Media Center application is included with Windows XP Media Center, Windows Vista Ultimate and Windows Vista Home Premium editions only. Note: the enclosed remote control is not MCE certified and does not replace Media Center remote control.
- ATSC TV recordings are not 100% compatible with DVD, and therefore you cannot burn them directly to a DVD.
- For use with Vista, the WinTV-HVR-1600 is certified for use with Microsoft's Media Center application. Not all included applications on the enclosed installation CD are currently certified for use with Vista.
- Some original models (specifically models 74551 & 74031) do not support clear QAM.
