ok, so i have an idvd encode going on, and it's frozen on the last stage..(encoding audio). when i say frozen, i mean it has a beachball..i can drag the app window around. it's been like that for about 15 minutes. does this happen a lot? i dont know because i normally leave it overnight..should i just quit it now or leave it and see what happens? it's incredibly annoying, especially after a 3 hour encode on a 6-month old computer..
