I thoroughly reviewed the referenced posting you provided in your above posting but unfortunately I could not any postings that you made in that thread.
AnyDVD-CloneDVD are proven software programs and the problem you are describing does not appear to be software related.
Since you are reporting a similar problem on two different computers strongly suggest that your problem is DVD Media related.
Request that you provide the actual Manufacture ID and Media Code of the DVD media you are experiencing your current problem with (Example- RitekG05). You can obtain the Manufacture ID and Media Code by using DVDInfo Pro (http://www.dvdinfopro.com) or similar software utility.
Suggest that you perform some Hard Drive maintenance to ensure that your system is operating correctly. Check your system for any Spyware that might be inadvertently installed by using SpyBot Search & Destroy (http://www.spybot.info). Then Defragment your Hard Drive (Start/Programs/Accessories/System Tools/Disk Defragmenter)
Also perchance do you have any UDF packet writing software applications installed? The flowing are examples of packet writing software programs â€“Drag-To-Disc, Direct CD, InCD, DLA (Drive Letter Access), CE Quadrat Just!Burn, File CD, Sony abCD, InstantWrite, Backup4all, B's CliP, NeoClip. Packet writing software applications are very problematic, cause numerous conflict errors, and frankly donâ€™t work as advertised. Strongly suggest removing any and all packet writing software applications.
Items that have proved to be problematic when running in the background while Burning a DVD are some Anti-Virus Programs, Peer-To-Peer File Sharing Programs, and Surfing the Internet. Burning a DVD is a demanding task and it is just wise and prudent not to be multi-tasking when Burning a DVD.
