I've been tied up with work a lot lately and haven't had a lot of time to spend on it. I still haven't been able to overcome the problem with the resolutions at 108Mhz, otherwise it seems to work pretty well. I expect it will be a while yet before I can spend any serious time on it, so if someone else wants to work through the problem and submit a patch, feel free. Regards Tony Prisk
