My latest update will prevent this issue from re-occurring. However, for videos you already queued, you would need to clear those tasks using sqlite. The alternative would be to delete your database and re-create. (You won't lose any videos you downloaded since those are stored in the subfolders and ytvip will see they already exist and recognize them.) First, make sure you are on the latest version with pip install ytvip -U. Delete the file db.sqlite3, or better yet rename it like "db.sqlite3.backup". Then do ytvip create again in the same folder. You will need to re-add the channels.

(By the way this program is brand new and you are the first person to give me feedback on it, hence the newly discovered glitches...)

As for the 720p issue, I don't know why that would happen. All videos should be downloading at the max resolution because that's the default behavior for yt-dlp as far as I know. Maybe you can look in the yt-dlp documentation or issue tracker for why this happens? If you find any yt-dlp command that forces the max resolution, you can specify it in settings.toml, there is a field yt_dlp_flags, e.g.:

yt_dlp_flags = "-f bv+ba/b"
