Hi, I hope this has not been answered elsewhere, i have searched but could not find anything directly related. This is my problem.... I start with avi's/xvid films that i have downloaded, then using MainConcept Mpeg Encoder I create an mpeg of the film. After this, i then create vobs using TMPGEnc DVD Author and once these are created shrink them down using DVD Shrink, so that they are the right capacity for a standard DVD-R. Burn these new vobs with Nero 6 as normal at 2x onto Ritek Grade A 4.7Gb Printable Blank DVD media. My main problem occurs when I try and play back the dvd using Cyberlink PowerDVD. The film runs fine for a about 30 minutes, and when I skip the film through PowerDVD comes up with an error, saying that the disc is possibly damaged etc. However, the disc looks perfect, and I have been recommended that Ritek Grade A should be almost 100% and thus no errors should occur due to the disc's. Could someone please give me any guidance?!?!?! Grateful of any help.... Andy/Student.
