When i use Nero it ALWAYS says my movie file is too big. Then asks if i want to reduce it to make it fit better on a single layer 4.7gb disc (I'm guessing that's DVD5) When i hit yes the file is drastically reduced and the playback quality is horrid. I decided to play with Neros Recode a bit and see if i can ratchet down the file size manually and fill the entire DVD instead of the huge cut i've been getting. But i can't seem to figure out how many Megabytes can fit on my 4.7gb DVD's. At first i recoded them at the obvious size 4700mb. It went over by like 950mb. So reduced that by 950mb....and it was still over by 950mb. What's the biggest amount of MB's i can recode a movie to fill my 4.7gb discs?
