What's your thoughts guys, would I still need the software update to ensure surround sound compatibility via the coaxial input?

I purchased the switch mentioned above however in having a few issues. Firstly with my two Satellite recievers, when connected to the switch the images are shown but in pink. I was thinking it may me the DVI>HDMI cable connected from the switch to the TV however if I bypass the switch and plug directly into either reciver the picture fine. The other issue I have is that if I connect the Apple TV to the switch I get no video where as he other devices connected show in pink. 

i have tried the switch on another tv and it appears fine, any ideas? Could I need a different brand of switch?

Any thoughts guys on why I'm getting a pink video feed via the switch, do I need to configure the tv on a specific output I.e pc??

Any thoughts guys, don't mean to keep bumping this thread but I'm not sure what I need to do. Do you think I would have better results with a gefen switch?
