Sure. Do you actually do that? I have done similar tasks, and was REALLY glad to find an inexpensive solution to end such crazyness.
I did it for 3 years with a 2009 Mini without issue. It took less than 2 minutes to make the switch, and it's not like I did it every day. That 2009 Mini is now permanently installed next to my TV.
But you are certainly correct about the OP's usage, he said nothing. Perhaps he will return to clarify so we can help more efficiently. Although I think you can hardly fault a person for assuming one would watch DVDs on a TV.
His original post doesn't even imply a TV:
what i want to do is copy my bought dvds to a hard drive and plug up the drive to my computer whenever i want to watch anything.
