Hi,
I think I've figured out how to do this. As I mentioned, there are VGA connectors on both the TV and the laptop (Windows 10). So, I transferred the video files to a Vantec USB 2 enclosure (containing a small ide drive, 2.5"?). As luck would have it, the Vantec enclosure will run off the USB drive (so, I didn't even have to use the power adapter). (If I'd had a larger drive on the laptop, I could have skipped the external drive.) One of the TVs (we have two) will show the files on the laptop (probably a smart TV), the other will not ( probably a dumb TV). And that's it. It seems to work. I haven't played an entire show yet, so ....
Thank you all for your help.
...... john
