I compiled a project on DVDA and tried to burn with Nero 6 and I get these errors:
DVD-Video Files reallocation failed.
File size is not a multiple of a logical block size (2Kb)
burn anyway = Yes.
The discs still come out fine, in my experience. All DVD-A prepared files seem to do this.
Burning within DVD-Architect is an option that some are able to enjoy (depends on the make/model of recorder). I always use Nero, in fact I always write an Image.nrg and then test that after mounting it as a logical device in Alchohol120% and my software DVD player first. I also give myself the option to use a DVD squeezing program if the image is too big for DVDR _AND_ certain chapters/titles can suffer this squishing. Discs being 99% full hasn't been a problem for me yet, with this extra workflow.
I'm keeping the original nrg online just in case I can afford a DualLayer DVDR later this year. Then I could remake some of my works with that extra definition. I'm interested in InterVideo DVD Copy Platinum for making compilation DVDs from my smaller projects. It appears that it supports multi-VTS even if the original is single video VMG like DVDA seems to make.
Here was my post from that thread. Perhaps this will help:
First a disclaimer: This works for me, but your mileage may vary ...
I use Nero 5.x, not the newer 6.x. Normally, I prepare AND burn using DVDA. However, often I want to put additional files on the DVD (MP3 files, picture files, etc.). You can do this, provided you put them in a directory other than VIDEO_TS and AUDIO_TS. Now, it is possible that this violates the DVD spec, so I don't do it for disks I am sending to other people, but I do it all the time for my own DVDs.
In your case, as I understand it, you want to use Nero because it can control your DVD recorder whereas DVD Architect cannot.
If you prepare the DVD in DVD Architect, and then use Nero to burn, then you will probably get the error message that you referred to in your last post. This issue has been discussed a lot, both in the DVDA forum and also over at doom9.org and dvdrhelp.com. Some say that DVDA doesn't prepare the IFO files correctly (that is what came out in the DVD Shrink forum, and I did verify that if I simply copied the file set using DVD Shrink 2.3, from one directory to another, I no longer got the message -- the only files altered were the IFO files). I don't know. You can use this DVD Shrink "workaround," if you wish. However, the workaround that has been used since this first came up last spring is to use Nero's UDF template. This keeps the DVD Architect IFO files intact, and many people point to DVD Architect's compliance with the DVD spec as one of its biggest strengths, so you probably don't want to "diddle" the IFO files if you don't have to.
Here's how:
Instead of selecting the DVD Video template in Nero, select the DVD-ROM (UDF) template. Make sure you select "File System Version: UDF 1.02". Do not check "Force DVD-Video compatibility mode" (unless you are burning for Xbox players). You then drag over your VIDEO_TS and AUDIO_TS directories from whereever DVDA created them, and you burn. It's that simple. You will not get an error message.
As I said, this works for me, and it has worked for lots of other folks, but it is unsupported by either Nero or Sony. However, it may allow you to use your burner, and it certainly will allow you to put other files on your DVD disks.
Try it on a DVD-RW, if your set top player can play it.
For what it's worth, I use DVDA to prepare the files and Nero to burn the Dvd's. The setting that I use is the DVD-UDF/ISO option. I then just drag the video and audio folders over and burn.
I'm not sure what the difference is from Johns method (UDF vs UDF/ISO) but it works for me.
