I'm new here. I wish to record some recent historical events that ended up on You Tube that I wanted to record for posterity. However when it came time to record using Roxio Toast Titanium 12, I was informed that the four files were not in the format to be able to be recorded. This is the first time I've needed to do this and of course the first experience of having run into this anomaly. Any advice from experienced videographers would be greatly appreciated. Thanks.
