New user to Channels DVR, but longtime of DizqueTV for Plex. So far I've found Channels to be much more stable and reliable than Diz, but Diz is a good bit easier to manage and configure custom channels, probably because it uses the Plex media manager instead of it's own like Channels does.
A few things I've noticed that seem a little weird. When adding a virtual channel and adding content, sometimes about half the checked media doesn't get added. I've verified multiple times that a particular video was checked, then it doesn't get added to the channel. Many times I've had to do 3-4 rounds of "adding" to finally get all the media added because the system can't seem to add more than 8-10 items in a single go-around. And every so often, when selecting "Custom" for the order, I cannot rearrange titles. Sometimes it works fine, but sometimes after I drag a title to a new place, it'll snap back to it's original order and then open the media page for that title. Not sure if this is a Channels thing or something screwy going on with Chrome.
Searching by Labels doesn't seem to work at all. I have several MST3k episodes and I didn't want "MST3K" in front of all the titles, so I put a "MST3K" label on all of them. When I search for "MST3K"....no results.
A little more selection/customization of the scraper ops would be nice. I've got several TV shows that don't get matched to anything but still appear on many TV DBs. Not sure what scraper Channels is using but it would be nice to be able to give it an alternate scraper to use if needed.
And honestly, after painstakingly editing my metadata in Plex and finally getting everything to show up just right, having to do it all over again in Channels is bit of a pain, especially since it doesn't seem to be as flexible. A Plex Library import would be really nice.
