I have a problem in VDR that sometimes when I change channel I just get corruption displayed on the screen and choppy sound. If this happens I have to tune to a different transponder and back again to get the channel to show correctly. Some times I'll have to do this 2 or 3 times before it'll work. I don't know what's causing this, it happens with both encrypted and FTA channels. I've adjusted my PWM value on my FF card, so I get AFC of (-1) or (0) each time, and I get a frontend lock all the time. Has anyone come across this and does anyone know of a way to either stop it happening, or automatically tune to a different transponder and back again if it happens? Many thanks, Chris
