Not sure if it is a firmware bug or a problem with IceTV server; the new firmware and the server migration happened about the same time

. It could be a combination.
I have not seen this (I've installed this firmware twice on 7100+ and 4 times on 2400), but that may be because I do a factory reset
both before and after installing new firmware. However it definitely can happen -- I have seen it at lest once unsing earlier firmware builds.
I am confused about what the Reset EPG data is supposed to do. It was originally intended to deal with EPG data corruption, but that issue was fixed in the November firmware. I'm sure I've seen instance where it appears to do nothing, in other it refreshes the EPG data and I'm sure that I've seen it remove all timers (but this may be faulty recollection on my part.
