I'm having a hard time with my memory here. I seem to remember using 3 or possibly 4 different versions of AzboxEdit, and I'm not positive which firmware versions I used each with. At some point they had to change AzboxEdit to work with newer firmware, and then at some point people stopped using AzboxEdit, because there were more changes in the firmware that killed it to some extent, but I'm not sure when each change occurred.
I know that I now have on my computer a versions 0.9.2371, 2880 and a version 2880a. My Azbox came with 2371 firmware, so I may have started with that version of the editor, however I may have tried solving my problems by upgrading firmware first, so I may have used the 2880 first, I'm just not positive.
I THINK (hopefully someone with better memory can comment) that I was most sucessful with 2880a editor while running firmware version 3877 , but it may have been that I used the earlier 2880 version with another earlier firmware version, and then switched to the later firmware and editor. I'm just not sure, however I do seem to remember that 3877 was the most stable of the Azbox firmware versions, and I only switched from that because I wanted to try some of the streaming capabilities of later firmware versions. But I'm pretty sure that the AzboxEdit 2880a works fairly well with firmware 3877, and I think that the more recent firmware versions could use the DVBS.dat files from 3877. So I think that using 2880a would be the one you want, but again, hopefully someone else with better memory can help.
Anyway, I tried to find the link where I downloaded it, but couldn't find it. I googled, AzboxEdit 2880a, and came up with several links, any of which should be OK, but I'm not sure which I used. It DID come as a rar file, so I needed to unpack it, and if you don't have a program to unpack rar files, that could slow you down. So I took the files that a RAR unpacker creates, and zipped them. I tried to attach them here, but the file was ~ 6.2 MB, and the limit was ~ 4.5 MB, so it wouldn't let me attach it. If you can't unpack the rar versions you'll find by Googling, I can send you the file via another method. But I think version 2880a is the one you want.
