Hi, Eric!
I did not mean to sound pedantic on the subject, but I've come to value the ability of being able to hold the cursor over any video or MP3 music file and see its playing time, so that I can calculate how much I can squeeze onto a DVD or a music CD. To that end, I write down the playing times on a sheet of paper, then add them up. Counting the seconds, if you add 45 to 33, for instance, instead of 78(which is adding figures normally) what you end up with in counting time, is 1 minute, 18 seconds. likewise 45 + 33 minutes = 1 hour, 18 minutes. The trick in adding time is NOT to go by normal convention. Adding time goes from 1 to 59, the next number up, shifts from second to minute, or from minute to hour.
That should help when next you calculate how much video you "shoehorn" onto your next DVD. If you're using an earlier version of Power Director for the authoring, set the burn profile to DVD-SP and you can squeeze 2 hours, 25 minutes quite easily onto the disc.
Cheers!
Neil.
