I have this same issue to. I'm new to Channels DVR, but the creating "pass" for shows I want to record seems fairly streight forward. But, after the intial recording , nothing else is recorded unless I manualy record the show.
I must be doing sometng wrong, but What?
New episodes, keep all, any channel
Try getting rig of New only.
If that doesn't work, it's usually bad guide data that doesn't identify each episode as unique.
For one that doesn't work, what is the source for your pass and what do the settings look like?
