Hi guys i just finished a 1hour 50 min film took 5 hours to render which i thought was pretty good, the thing is tho i altered the bit rate settings, anticipating the 4.5 gb limit on dvd-r's. I dropped the 8000 down to 6500 and the average 6000 down to 4500 but on the subsequent dvd the quality is not quite good enough and also the final film size was a lot smaller than i thought. How can you alter the bit rates and know the final film size before you render and what figures would you use for maxium quality but with a way to get around 2 hours worth crammed onto a dvd-r .

I use vegas 5 but not architect i use meastro cos i want total control over the dvd format.
