More things that can cause the skippy hiccup:
Media write speed–so try a different speed.
Transcoding in use: Of course, Nero shouldn’t make a skip, but I use Shrink for re-coding to size, and then RecordNow or Decryptor to burn the resulting .iso file.
Presence of VSO’s Patton Couffin driver installed in Windows Device Manager
Nero’s INCD, Roxio/Adaptec DirectCD, Sonic’s DLA
Virus scanner switched on while reading, transcoding, writing
Norton Protected Recycle Bin is active
System Restore is active (use backup to cd instead and disable System Restore)
Hard drive needs to be defragmented
Data integrity slightly bad due to a defective or sub-optimal IDE cable.
Virus or spyware present on a system that has a constant internet connection (who care’s if you’re writing a DVD, it’s time to E-mail 95 more people).
3rd party IDE drivers in use/not up-to date
Media not compatible with set-top player–very common, try different burn speed or gift the incompatible media to a friend. But, don’t send it to me! I’ve got one of the crankiest set-top players possible. Although, firmware T9 has helped make most DVD+R discs work well with it. That was a fantastic christmas present from BenQ.
Not enough free computer system memory causes buffer to drop below halfway and the BenQ attempts to rescue the disc on media that is not completely compatible with the seamless link technology (on -R the seamless sometimes isn’t). This can happen if the software buffer is too small. It can also happen if the software buffer (in writing software–check preferences) is larger than the amount of free system memory, causing constant swapfile access during DVD writing. Check free RAM while burning a test disc and purchase additional memory if needed.
Too much 3rd party add-on software running while DVD burning. For instance, 4 different instant messangers, camera connect, all-in-one PSC software, weatherbug, NAV.
Automatic updates such as Microsoft Windows, Anti-Virus, Printer software, Realplayer, and SO many other programs will run in the background constantly checking for updates and interfering with DVD writing. A huge collection of these could create a memory/cpu lack similar to virus activity. Check the “run” section of the registry, startups, and services to see if your computer is overloaded by automatic updates.
P.S. I have noticed that encoding 3 or more videos simultaneously can introduce pauses into video. Flinching or pausing video can be fixed with NeroVision, subtracting the damaged section, and transcoding into a new disc. Transcoding takes much longer than recoding, but it will fix any timing issues that are video-file specific. I suppose that if a computer were overloaded while encoding video that it could screw up the timing, but you would experience these glitches on any set top player, not just one. So, I suggest that you have the usual problem of your set top player disliking your choice of media.
