Don't know cybes. Haven't ever really used an onboard editor. Probably because of the whole remote left-right-up-down thing. Using an old version of E-Channelizer and have been for years. The free version. I know some prefer the likes of Dreamboxeditor and the likes. Onboard editors just seem a little bit "fatware" to me.
I like the ease of scanning a sat. and downloading it into my editor. Shift-clicking a group of Digicipher, Nagra, etc., channels and deleting them. Same for selecting and ordering channels into an easily created and named boo-kay.
Not even sure with an onboard editor how you deal with channels that scan in as Program 101 and are really something different when using the likes of a chart from tvro. Same for picons (sounds like someone needs a dental surgeon). Name the channel correctly, drag the picons from the chart to a folder and name it the same as your channel.
Easy. But I could be wrong.
I did find that a lamedb backup from OpenViX doesn't play nice when uploading to TNAP. Channels were persistently out of order. I don't use TNAP a lot either.
Probably a touch off topic for your question. Just that sometimes finding a door to walk through is a bit easier than banging your head on the building until the mortar joints crack. At least that's what my shrink suggested.
