Command line youtube-dl & ffmpeg?

[Adeptus]

Hi all, long time listener, first time caller...

I've been downloading some shows from CBC (Canada), using youtube-dlg. But they end up with the sound drifting.
I found that using XMedia Recode, if I copy the audio & video to separate files, then copy them back into a single mp4, it fixes it all up.

So... I've been looking into command-line options, so I can build a batch file. Something I can feed a URL to, and get a finished product with no more user involvement.

It looks like with youtube-dl, I can download the audio & video as separate files?
I think I read that XMedia Recode uses ffmpeg - should I be using this to merge the streams?
How do I do this from command line?
I also saw that youtube-dl uses ffmpeg - would there be a parameter that I can change, that will fix the merge ytdl does, instead?
