Blank screen when switching from Online Services to Live TV

[sevi32]

Hello,

I am a new SageTV user, running the latest release version of STV (6.3.10). My HTPC is a low-end computer running WinXP. During the configuration of STV, I found that I get the best performance and TV quality was when I use Overlay as the Video Renderer and SageTV MPEG Video Decoder for the MPEG2 Video Decoder Filter. However, using these settings, if I am watching Online content or other video content and switch back to TV, the screen is blank but there is sound. The only way I can get the video back is to go into the Detailed Setup and change the Video Renderer from Overlay to VMR9, basically restarting the media player. Since the quality isn't as good with VMR9, I switch it back to Overlay and the video is fine, until I go to watch Online content and switch back to TV. Has anyone else experienced this same issue? Any ideas would be appreciated.
