Many thanx for your hard work and these beautiful things we keep getting from the community! The original FW for DBox2 is terrible!
Your work, on the other hand, is ab fab!!! 
I am just a sucker for the Open Source community!!! 
Having said that, I think we must give the proper, honest feedback, which will, bit by bit, result in learning and improving the FW and SW.
I'm a complete novice with DBox2. I have had some experience with Humax VACI, DSR Samsung 9500 VIACI, plus a bit with Galaxis McZap CI, Technomate 5200USB and Echolink, though. Done a few settings/channel lists myself, actually. I know what other, simpler receivers can do in terms of editing the list via remote...
Sadly, they have some of the functions better thought through than is the case with DBox2. For instance, so far I haven't discovered the possibility of getting into the list, then marking channels and then deleting the whole lot one chooses with a single OK button pressed. Rather, we must go through a laborious one-by-one procedure.
Worse still: the box wouldn't remember what one does, in such a painstakingly slow manner, and one can see, once in the channels list, how DBox2 is writing them back, one by one, when one returns to a satellite position. If one unplugs the box from the mains, then all is returned in a second. What does one have to do with DBox, please, so one's work would be respected and remembered?!?
My setup: polarmount moved by Pace1008IP old analogue rec; Philips DBox2 [flashed by an expert, as it had to be repaired, too, plus I needed an MC], with an external Multicam; PB Enigma 6.0.1; Satscan plugin downloaded; openDBedit 3.0.6. To begin with, the non-DiSEqC option for many satellites couldn't be remembered...
I managed to delete the channels in it somehow, I think by going to tuxbox/config/enigma and deleting all except config, then unplugging it from the mains, in order for the rec to memorise it. I needed to start from 28'W and wanting to go at least to 30'W. I went for it in a systematic manner all the way to 1'W, where I got stuck. I manually scanned all the satellites, frequently searching for a long time through all the transponders, to find the missing ones and all went well, more or less, until Thor/Intelsat at 1'W, where DigiTV could not be memorised at all!!!
The Philips DBox2 can find the DigiTV package, it even shows it in the "new/found tags", but can not put it in the list. I thought that was the case because it reached some 5500 channles, data and radio ones included...??
So, I went into it and manually deleted hundreds of channels, one by one [that is just wrong to have to do, guys!]! Sadly, they could not be permanently deleted, much to my horror and surprise, whether I put it in the Standby mode after the changes, hoping the new state of affairs with less channels in the list will be saved like that. Alas, they were written back, one by one, as soon as I came back to a satellite position where I deleted some channels. Or by unplugging it from the mains I would get the same result, more or less, because it all came back in an instant. I am mystified! And disappointed, up to a point...
More on openEDBedit later...
