WinTV FM & the video size question - please help

[spooky]

I have just purchased the WinTV FM (401) card, installed the drivers from the web, installed the app from the web & installed the FM app from the web. The Radio app is not that bad, the IR for the remote works fine, the Win2000 is not the greatest app at all but it works, but when I started up the VirtualDub & went to do a capture to try it out, the size was 320x240, it worked & the capture worked also. But when I tried to make the size bigger ( trying to capture at 640x480 or 480x480) it is not allowing me to change the size. Then i decided to install the BT drivers from Sonics website. That worked & once again I opened up VirtualDub and at 320x240 I see the preview video without any problems but when I go to change the size to anything higher then that it does not give me any errors but there is no video showing up ( the app acts like it is locked up but it is not ) the only way I can bring the video back is to change the res back to 320x240.
How can I change the res?
Also, when the BTdrivers are installed the remote is not working ( not that I care about it )
Can someone help me out please alittle with this card let me know how I can capture in higher resolution.
Thank you

This is normal. You cannot use overlay with any resolution higher than 320x240. I turn off the preview too (I couldn't even tell you if it works with it or not). Remember with the btwincap drivers, the hauppauge apps won't work anymore.
