I will try this later today and let you know. > Here's the philips table for your own experimentation: This table agrees exactly with mine for channels 21-69, which are the only ones used in the UK. These channels also seem be the same elsewhere in Western Europe. There's a list of channels for various systems at http://gemma.apple.com:80/dev/technotes/tn/tn1012.html Some of the other channels in the Philips list correspond to those listed for PAL B/G at the URL above; I suspect the Philips list reflects Dutch/German channels. -- Richard
