Hello, I have found an issue that appears to be universal for users with 8600M GT's.  The new dell drivers 174.31 (if I have it right) from the website kill TV-out on XP.  I had to roll back to the november drivers to get TV out working.  I have an XPS M1530, and it is running XP through the instructions posted on the web site, with help from some moderators.  When I updated, my TV flickers and goes black.  Under the control panel, it shows up as a TV, but it only comes up with autodetect as the source, it no longer shows S-Video.  When I roll back it works fine.  I even tried the new drivers from Laptop video 2 go.  It does not work at all.  Is anyone having good luck getting it to work?
