I have a Pio 433HDE with the Pio PDP-R03E tuner box and I'm having an intermittent problem with it. Every so often (5 times in the month I've had it) it stops responding to any control pins on the SCARTs. i.e. no widescreen switching, no automatic input select and the SmartLink light on my VCR goes out. A reboot of the media box fixes it, but it's still annoying. Has anyone else had this, and if so, did you get the box replaced?
