FYI, I borrowed a (completely different - vendor, model, etc.) tuner from a friend, to see if this was related to my DVR. Tried it on both Linux and Windows servers (one using the built in EPG, the other XMLTV input) - in both cases, the EPG seems to be getting modifed by the Agents (i.e. searching theTVDB).
Any way to avoid this?
Thanks!
