Hi Peter,
I'm not sure what the Philips rationale is, but the video input mode switching is available on some models and not others. Ironically, I would have expected this very necessary “feature” to be available on the higher-end models that generally have a large number of available video modes. If they were to be included anywhere, it would be natural to assume that the feature was available on their HDTV models. Alas, this was not the case with my top-of-the-line VERY EXPENSIVE model.
I'm not at all familiar with the 34PW9815 you have so I can't comment of whether or not there is a work around to the problem. If you haven't done so already, you may want to visit the CCF downloads area and try ccf’s from other Philips TV models.
Also, someone recently posted a work-around for the Philips 32PW9616. It didn’t work for me, but with any luck, it’ll work for you. The thread can be found at:

Good luck -- Steve
