Using Main Concept to encode and compress for DVD burniing causes me to lose from 7 to 20 minutes at the end of the movie. On a file of 5.6 GB, I encoded to 4.1,3.9,3.5 and 3.2 GB and still lost the end.I use DVD, NTSC and Layer 2 audio or LPCM. In details, I use 2 pass VBR and file splitting and I have used Sequence Extension. What am I not doing or what dumb mistake am I making? Thankyou in advance for any help.
