That’s seems odd, that the second time using Clone it burns at 12 minutes.
Do you have any other burning programs that are running which may conflict with CloneDVD? If by chance you have any packet writing programs installed, by all means uninstall them, nothing but problems with them.
Also try disabling any AV programs you may have running.
Last suggestion for troubleshooting purposes, after CloneDVD rips the files and asks you to insert a disk, exit CloneDVD by the close button on the top right hand side of screen, DO NOT HIT CANCEL, or you wil lose the temporary files.
Then open up CloneDVD again and hit the third button on bottom, “write existing data”.
Navigate to the temporary folder where the movie is stored and click on the Video_TS folder. Also make certain that the 8X speed is checked in CloneDVD and use the 8X Verbatim media, not the Phillips.
See if that works and we’ll proceed from there in getting to the root of the problem.
Edited: I believe your problem may be with your firmware.
Since you have the Liteon 1633S the CSOP firmware converts this to the 1653S using Liggy and Dee’s firmware. Why don’t you try flashing back to the BSOS stock firmware that it the latest for the 1633S and see if that corrects the problem. You can always flash again to the CSOP.
You may have tweaked something with the Omnipatcher that is causing this slow burn.
