Nero vs DVD-A: Why different results?

Ok, now I'm confused. Why would it make a difference if I used Nero or DVD-A to burn the DVD? It's simply laying the bits on the DVD that are already on the hard drive, right? They should be exactly the same shouldn't they?

I created a DVD for some people at church and several of them couldn't play them. These were all burned with DVD-A. One person that couldn't play the disc has in the past played DVD-R's that I have created using "MY-DVD" that came with my A03 so I know it wasn't the media. (I always use memorex DVD-R). On a whim, I took the directories from the hard drive and burned them with Nero, and behold, it plays just fine now. Now I'm thinking I should always burn with Nero.

This just doesn't make sense to me. Can someone explain this to me please?

Thanks
Michael Hampton

Are you sure it wasn't just a bad disc?

Yep. Tested the disk on my pioneer dvd player that plays just about anything thrown at it. Worked fine there.

When is a DVD for Video not one....

well the layout can change from the outset. Some DVD authoring tools use DVD-Video book types, others DVD-ROM. Apparently the latter is better for many decks when they deal with general media (non pressed) DVD.

Then the layout on the disc can be ISO-9660 or UDF (usually the latter with an early type for percveived compatibility).

Then the order of the files written can have different "sector" overheads due to that specific chosen order.

Also the version on your HD can take more space than the disc depending on whether the DVD authoring tool you've used writes raw NTFS sectors or NTFS "user files".

Nothing is created equal and one line of understanding that can suit most of your target players won't suit the remainder.

The DVD format for video is either reverse engineered, or read from formal recommendations. Either way, room for interpretation is present. Programmers are intelligent but that can be where they come unstuck. Assumptions etc.

Trust DVDA to build the folders and Nero to do your burn to DVD-Video. IMHO.

That way, we can push SoFo to add more video features to DVDA and not more writer support. A waste of their precise skillset.

Richard,

"...That way, we can push SoFo to add more video features to DVDA and not more writer support. A waste of their precise skillset. "

You "stole my thunder." Needless to say, I fully agree with everything you say, including your good explanation of why there is more than one way to burn a DVD. I also agree that letting DVDa make the files and Nero burn them seems like a good division of labor.
