MKVToolsNix is how I remove audio tracks I don’t want from MKVs and reset default tracks and subtitles. Super easy to use.

I pulled down Tubi’s 720p release and it’s good enough for a videotape based show.

Also, FT Depot on YouTube has nice 4K film scans of the two 20th Century Fox movie shorts of Mr. Bean from the 90s which are also must haves.

Sony (Columbia / Screen Gems) has several legit YouTube channels and uploads old TV episodes and movies. Some of their channels are Throwback TV, Classic Rewind TV, Stream City and many others.
