and i first tried with a tv show episode, a 350mb file ,and everything went ok, it took about 40 minutes to finish

but when i tried with a film ,a 700mb file it took 2 hours and 20 minutes just analyzing source ,is this normal??

it took more than 4 hours to finish the all process ,in the end the avi file was ok, but 4 hours is this the normal time??
