Right now (tvengine3-03-25-2007--01-13h--Rev13562) channel setup is a real tedious process. TVE has some auto-scan option but it still requires a lot of extra work after the scanning is done (renaming, removing non-real channels etc etc). The old tv engine had a database with channels which made setup a breeze. In order to have me test this new engine more, this setting up should be a lot easier. Especially since every now and then the database is reset after an update.
So, my suggestion: use the channel preset database from the old engine.
