Ive been using gordian knot for a while now and it gives me this error sometimes i dunno why. I captured a music video at dvd resolution at 720x480 and i have done this before too but this time i set the file size to come out to 50 mb but after i run gknot 2 pass xvid i get files around 150-200 mb. any idea what causes it ? im not even encoding audio i already have the audio as ac3 and im just muxing it.
