IPTV m3u Playlist Malformed

I've been working on adding a custom playlist generated from m3u4u, and running into errors when uploading to Channels. As a testing exercise, I attempted to use the examples provided here (https://github.com/fancybits/custom-channels-examples) and receive the same error -- malformed m3u playlist. I've just installed Channels DVR yesterday so I know I'm up to date. Any suggestions on what I may be doing wrong?

Thanks!

I think you should stop using that m3u4u and mov3e to a real editor.
Threadfin and m3u-editor can do exactly what is needed.
Lists are usually quite large and i'm finding that using stuff that is steadily kept up and help a lot.

yeah in my experience m3u4u is just terrible, a real PITA, and more trouble than it's worth. I'd been using Dispatcharr for awhile now but hear great things about m3u-editor too.
