1498 and1499 have guide data. Have you tried using a Wish List? You can set up key words and have them auto-record your shows. (Or will it not pickup the 4K channels at all?) 1494 and 1496 just say "to be announced" so manual recording is the only option.I did manual recordings for the games i wanted before exploring the onepass route.
For onepass, i eneded up setting the channel to 1499, and manually checking 1498 forany games i had missed.
They either need a 4k option for video quality on the onepass, or the ability to specify multiple specific channels to restrict the onepass to.
