How can I use an old internal hard drive as a DVR or media player?

I want to know if there’s a way to use an old internal HDD as a DVR or media player. I have an old Sony Bravia that only plays MPEG1 movies through the USB. I would be nice to use my old HDDs to play movies for the kids. I also have the three color RCA inputs as well.

Thanks in advance
