You will find that XchannelEdit has a quite different approach compared to the DVBViewer channel editor. It works in a very direct way on a copy of channels.dat but should be quite safe to use since the channels.dat will never be overwritten unless a successfull backup has been taken.
Thanks to Griga for redocumenting channels.dat (It's good!) and to CiNcH for providing me with a big sample channels.dat (DVB-T and DVB-s). This is the basis for me daring to provide a quite detailed Channel Info. Please check if the Channel Info is correct and feel free to suggest improvements.
