First off, thanks for looking and taking interest in my troubles.... Im having some problems with DVD Shrink v22.214.171.124 and Nero v126.96.36.199. With the DVD Shrink... im having trouble keeping it open. When i start the program and then open a DVD into the workspace, everything goes as planned. It does its mini analysis and then the options pop up where i can pick and choose which parts of the DVD to keep or remove. Well the problem comes up when i go to click on any of the options... lets say "Main Movie". An error pops up that reads "DVD Shrink 3"... inside it says "DVD SHRINK 3 caused an invalid page fault in module QDVD.DLL at 016f:02225e31." and im forced to close the program. I know how to go around this problem, simply by opening two seperate DVD Shrink windows. That does the trick. But i Can't understand why i cant use it on simply one window. On a separate Issue.. i noticed that when i decide not to choose "Enable Video Preview" during analysis/encoding, the speed goes up. Does this affect the quality of the rip or doesnt it. Onto Nero. The problem i have is with the burning process messing up at the very end. It fails when it is writing the lead out. It happened three times in a row. If it does happen to complete, i use the verify the disk option in nero and i always find inaccessible areas at the very end of the disc. When i later play the DVD i find that it freezes at the end points of the movie. I just recently set my drive to DMA mode to achieve a 4X burn speed and it did that, but i have only finished one DVD and failed on 5 others. I unchecked DMA and burned at 2X and i successfully burned the same DVD. I dont know whether the actual DVD disks are causing the problems or if its my settings. I noticed that when i had it on 4X, the used buffer was always at 100%, while at 2X it would go down to 0% and climb to stay at 100% for only a short time. How does used buffer affect the burn? I think my LiteOn LDW411s (firmware FS0F) only has 2MB. Can anyone please let me know whats going on? How can i get my success ratio to go up. Can anyone tell me what settings i should use on Nero. Thanks for taking time out to read this. *** i just recently installed AOpen DVD 1648/AAP dvdrom drive. i changed to DMA setting around the same time i installed so i dont know if the new drive could be causing the problems too. the disks im using are DVD-R Ritek Ridata G04.
