Vegas 6.0 conflicting with my TV Tuner.

Hi everyone. I have a video dilemma with my PC thats really bugging me, hopefully an editing guru may know a solution. Theres this really great program, Sony Vegas, and its like the best editing software on the market, at least to my knowledge. On my PC I have 2 TV Tuners, ATI Theater 560/660 (not sure, came with the new PC) and an old ATI TV Wonder VE. I've had the TV Wonder for years, and its worked fine with Windows MCE, until I installed Vegas. Somehow, Vegas is overriding my old tuner, and the only way for me to access it is through DScaler. Everytime I try to use it in WinDVR, Movie Maker, or Vegas it says 'overlay not available' or 'device already in use.' My new tuner works fine with no problems, its the one I use for watching/recording 'TV', the older one is used for playing/recording 'Games.'

I made a post on TheGreenButton, if anyone wants to look over it for more details please do. http://thegreenbutton.com/forums/thread/127032.aspx

But anyway, if someone knows how/why Vegas is making my TV tuner unusable, please let me know. Especially if you know of a way I can fix it so I can keep Vegas and still use my old tuner like normal.

Thanks in Advance.
