media center help needed

I have just installed Windows 7 and now im having trouble with my tv channels being slow to respond after changing channel or not responding at all (blue screen, saying no signal, etc), i have tuner pluged into roof mounted antenna so signal shoudnt be the problem. When i used my tv stick (kaiser baas kba01008 tv usb stick) with vista it was excellent quick to respond between channels and had the same signal setup as now what else could i try kasier baas dosent list any update drivers for my model no what can i try??

Do you have a link to the product page of that driver, as I can't find anything for it when I use Google? There may be some updated generic drivers somewhere if it uses a common chipset.
