When I try to list videos with playlistItems.list, I seem to not be getting the channelId of the video anywhere. The video owner is different than the playlist owner, mind you.

Here is an example in Google API Explorer

I'm requesting one item from the playlist with an ID of PLgMGySfO8dl_IybGLflF1QhHwhBkOyZg7. The one item returned is a video with an ID of tDHxiDA1Y6s. I'm expecting to see the channel with an ID of UCOfEKi7Qkc3g5XNoQSl3D8Q somewhere, but I don't see it.

I do see UC1bSfMYJEqh7DTSOsbe_t8Q as a channel ID, but that's the channel ID of the owner of the playlist, not of the video. Also I noticed in the fields editor that there should be a field snippet.resourceId.channelId, but even if I have it selected to be included, as you can see in the example result below, I do not get any value there.

Is there any way to get the channel IDs included of the videos without a second request?

This is the result I get:

As you suspected, a call to PlaylistItems returns the channel ID of the playlist owner. To get the original channel ID of the videos in the playlist, you'll need a second call to the videos endpoint with the video IDs.
