I'm running a portable dvd player into my MMCS system at the system, and for some reason after ~20 minutes of use the display loses the colours, and at this stage I'm not too sure if it is the tv tuner or the dvd box, and I was hoping someone would be able to loan me their tv tuner for a week or so to test it out.

I'm going to aussie Thursday morning, so it will have to wait until the new year, but hopefully one of you guys will be able to let me know now
