Did you fresh flash when you updated to 037?
yes I did - epg now looks complete (although not sure if this was because I updated manually yesterday). Going to see what happens tomorrow, if it still looks dodgy, thinking of flashing from scratch and not restoring any settings (take screenshot of them 1st of course), to see if that makes any difference.
I added another dual tuner card in to my duo2 about 3 weeks ago, didn't notice any problems after (but possibly I just didn't notice them) - maybe something to do with this
