Record one channel only

Hello, my first post, Im a newb. I want to record a program only from one channel but when I specify to record just one channel, it does not record at all. Example: Bugs Bunny and Friends on our local station in HD is 21.1 MeTV but the show is also on shows on 21.6 in SD MeTv Toons.

When I put 21.1 in the "Channel Number' Field -it wont record, I have to allow all channels.

Am I doing something wrong?

Have you ensured that you are set to record all episodes, not just new ones?

yes all recordings are chosen

Ok, I edited it again, and now its showing just the one Sat morning recording scheduled and nothing for 21.6. Hope it records! Will report on Saturday.
