I have a 17inch G4imac with maxed ram at the moment i can not seem to burn a successful DVD. I have managed to use idvd to do video dvds in the past but now i am unable to burn a simple data DVD with the finder. I try to burn about 4 gigs worth of filesat 4 different speeds with 2 different types of disks but cannot seem to get it to work. Everytime i get the buffer underrun error code(took some research on my part to find that out) Any work arounds? Apple as usually would like 50 dollars to fix help me out and frankly i don't think it is a 50 dollar problem. Any input would be appreciated
