I thought I would try to throw this problem to any Nero gurus out there.
If I use VirtualDub to convert some stuff to something I like (which is most of the time, especially if the aspect ratio is wrong or there is more than 1 audio stream or it needs cleaning up) I get a good render and the output looks great when I apply contrast/sharpening filters to brighten it up. I can't seem to get any audio from the MKV input filter so I have to convert that with something else first.
The next stage is to re-render that into VOB files to burn to DVD. I hate wasting DVD's so I frequently put related stuff all together onto a single DVD as long as the resulting quality is pretty reasonable with no pixelation.
For that, I use Nero (v6 Powerpack or v9). I've tried a few others like Pinnacle Studio (v9 & v14 HD Ultimate) and Ulead Video Studio (v6, v7, & v9) as well as Ulead Media Studio Pro (v6) and Ulead Movie Factory (v6) and I can't get on with them at all. I just happen to like the way Nero works and the way I can change the menu around, produce big Video_TS folders and shrink them to fit onto a standard DVD (DVD Shrink).
The problem I seem to have isn't consistent but does occur a lot of the time - Nero (either version) will pause briefly every 30-31 seconds while it processes the files. I have no idea why as I often leave these running at night when I'm not doing anything else (after a fresh reboot) and there doesn't seem to be any reason as to when it's going to pause or not. It's done it on a single Wallace & Gromit file that only plays for 12 mins and it's also done it on a large collection of clips (more than 5 hours playing) all squashed/shrunk from a 23GB TS folder and just about every combination/length in-between! Many times I just re-do it and it doesn't pause.  I can actually see the pauses by watching the performance in Windows Task Manager (activity plummets briefly) and the video window in Nero screen output freezes for a second or two.
I try to generate DivX 6.9.2/AC3 48K stereo files as much as possible to be consistent with everything else I've done before; or if that's not possible, an MP4 video file.
It doesn't seem to matter whether it's an AVI or MP4 video compilation other than the speed at which Nero re-renders it and around 60% of the time it will do its pauses. I always write to a hard disk folder, never to a physical DVD.
The resulting DVD is remorakable to say the least. It's usually very good quality (audio and video) but it "stutters". When it stutters it's only for a fraction of a second, but a definite stutter and it's at regular intervals all through the DVD. When Nero is slow (usually doing AVI's) it can be as often as 4-5 seconds between stutters; when it is rendering quite quickly (typically with MP4 files), it could be as long as 5-10 minutes. The original files I produce from VD (or AVS4You MP4 files) play perfectly without stutters so it's definitely a Nero hiccup.
Does anybody have any ideas why it does this??
Any help appreciated.
Setup -
VirtualDub v1.10.1-Test12, AVS4You v8.1 for conversion.
Windows XP 32-bit, up-to-date SP3, 4GB DDR3 Ram at 1340MHZ, Sata 3 HD's.
Intel QX8400 Core2 Quad CPU at 2.72GHz on Abit IX48-GT3 motherboard (Corsair H80 water cooling).
No other user processes running except AVG Internet Security v9 & physically unplugged from the 'net.
I have allocated a dedicated Nero work area (I don't use the default on drive C:) and I always do a CHKDSK and Defrag before rebooting to start these tasks so everything is clean & tidy with no lost chains/clusters, corruption or fragmented areas.
I also make sure the source files and the target Video_TS folders are on physically different drives each with at least 100GB contiguous free space so there is no drive/space contention.

Try burning the output using ImgBurn to see if it's actually a Nero problem. |

Also be aware that DVDs only support two frame rates, either 25 (PAL) or 29.97 (NTSC) frames per second. If you are trying to burn a video which was encoded at a different rate, I can imagine that might cause problems with some software.

This is before anything is actually burned onto disc or even shrunk, so this is definitely a nero problem.
I can play the IFO file (and let WMP follow the structure) and see the result - it stutters.
I can even play the VOB files directly, it still stutters.
Everything is always set to burn as PAL at standard frame rate.
As far as I can remember, I have never burned NTSC content as I live in UK which is PAL.
I never actually burn the image until it's all done and ready.
I usually test it by mounting it via Daemon Tools and letting WMP play it so I can see the menus etc are setup as I like them and that it plays automatically as I want.
Once I do burn the ISO image (after shirinking) I'm using Imgburn v2.5.5.1.
One of the confusing things I found was that I can often just "re-burn" the same project without exiting Nero and it'll work as expected without the stutters. There are odd occaisions where I may have to do this a couple of times to get a clean result. But I don't change anything, I just re-do it.
Weird!

I used to use Nero but had issues. Converx to DVD solved the problem. Plus it's so much faster. |

I already have "Converx to DVD" and it doesn't let me do what I want to do.
It also won't handle huge Video_TS folders very well either.
Not an option, sorry.
I know someone will come along and suggest Roxio too.
That is also not an option because they don't support my 99min CD's that I use - Nero will.
I ditched Roxio years ago and won't ever go back.

The one thing I recommend to anyone with issues like this is to make sure its not a registry error.
The easiest way to find out is to create another user in windows via the control panel and test the same process.
If you don't get the error, then its a registry setting which you can proceed to resolve.
If the same error occurs, then its something else and more digging is required.
Roxio used to be decent a long time ago but now its bloatware and lacking in features more and more.
I use Convert X to DVD with no issues. The reason I recommend it is because of the blazing encoding speed and ease of use. |

Have tried it on 2 other machines which have different hardware and one is rarely used since it was installed about a month ago and I still have the same problem.
I don't think it's a registry issue.
Convert X to DVD doesn't let me play with the menus - it just goes off and does it - which I don't want.
