Hmm .. I'm a satellite user and so no experiance with Dreambox & cable and not with Enigma1 also.

But what I can give as Help, is that dreambox has an Bouquet oriented Channlelist.

That means you have e.g. an own Favorite User Bouquet named e,g, "MyBouquet".

On the left side are your Channellist of all available channels read from the box after channel search run setup.

e,g,
channel 1
channel 2
channel 3
...

you drag the channel from left into the Userbouquet "MyBouquet" e.g. "channel 2"
then again "channel 3" an so on ...

"MyBouquuet" :
- "channel 2"
- "channel 3"

in this example has "channel 2" the number "1", channel 3" has the number "2" and so on how the channels are sorted accendly.
you can move / drag the channel in the Userbouqet on an other place ane therefor the channel has also an other number !

it is not nessary to add numbers in the channel name, there names will be overwriten anyway.

when you download the edited channellist / bouquets to the box with "sendfiles to dreambox" (with enabled autoreload) and to be sure that list will be loaded is the
best to execute after that also "Reload settings on dreambox" (will make an GUI / Enigma restart) where EPG data will lost, but channelsettings are vaild loaded.
