The only thing is different now is the operating system (Windows 7) on another HDD. The reason (and I’m sure you know about it) I started looking for the software like yours is because the support for Win XP is gone and I had to switch to Win 7 which only provides the resolution that it “thinks” is good enough for me with no additional options.

Windows 7 gets the available resolutions from the video driver. The video driver gets the supported resolutions from the TV's EDID. CRU overrides the TV's EDID, but that only works while the TV is connected. Your TV stops transmitting the EDID when you turn it off or switch inputs, which makes the video driver believe the TV disconnected. That causes Windows to rearrange the desktop, which is confusing the video player. That's what's happening. The HDMI audio information is also stored in the EDID, and the driver seems to be getting confused at some point during the disconnections and causing problems with audio.

The only way around those issues is to use a device like the HDMI Detective to continually transmit the EDID, which tricks the video card into thinking the TV is always connected. I did some searching and found this guy selling a cheaper device that does the same thing: http://www.ebay.com/itm/201052588124
