It'd be nice if there were consumer-ready hardware for something like this. I know a few people with VCRs (yes, in 2023) that still record to tape from their digital receiver and play back over composite.
I'm amazed that you can't just buy a device that acts like a VCR, with composite and line in and out, but records and plays back via digital files instead of tape.
I want to try this, perhaps using an older Intel Mac mini, but I'm wondering how to "sell" it to someone who just wants a VCR.
