First, DVDs can hold more than 2 hours. Just like VHS tapes, they have a high quality setting that hold up to 2 hours, but they have other modes that allow them to hold up to 6 hours, and some machines support up to 10 hours.
Just like VHS, the more hours you put on a single DVD the lower the video quality. Since you are transferring form VHS that should not effect you very much.
Your DVD recorder should support modes up to 6 hours.
Thank you PhilFrisbie! I really didn't know that. And I take it from your answer that 'since I am transferring from VHS that should not effect you very much'.....you are saying the quality won't be great, HD kind of DVD that one is used to with movie quality DVDs. Is that correct?
Actually being family movies, I'll just be happy to be able to have them to show in the future and laugh at how we all looked in the past! regardless of the quality. If they look like the VHS looks, that's fine.
Thanks for your advice.
