Dual Layer burn issue with TMPGEnc Authoring Works 4

[am_dew]

I just recently bought some TDK DVD+R 8X DL discs to use in my first venture into dual layer DVD creation and subsequent burning.

I use TMPGEnc Video Mastering Works 5 to create DVD compliant MPGs from my source clips and then TMPGEnc Authoring Works 4 (TAW4) to author my DVDs.

My first TAW4 project's burn (8X) was successful and plays back fine...that project contained 2 tracks, with each track containing 7-8 chapters.

The 2nd project however is another story. It contains just one track with 11 chapters and the total length is about 92 minutes. When playing back a DVD burned from this project, it stops at around the 42 minute mark (during track 6) and then the player can't read the disc. If I turn the player off and then back on, I can go direct to the start of track 7 from the DVD's menu and the rest of the disc then plays through to the end just fine. The same thing happens on several different players I tried, including a fairly new Samsung BluRay player. One Sony DVD player would not even open the disc.

I used TAW4's disc burning tool to burn both of these discs at 8X speed.

I also tried using a different burning program to burn the 2nd project at 8X and got the same results on playback, stopping around the 42 minute mark.

My next attempt would be to try burning at 4X instead of 8X.

Any other suggestions?

I wonder why the first project with two tracks works just fine? Could the fact that it is two tracks have anything to do with it working?

How does TAW4 determine where the dual layer split point should be? Is that layer split point built into the DVD files or does the burning program determine where it should be?

Thanks.

TDK discs are garbage....at least the single layer ones are anyway. I'd imagine their D/L discs are just as crappy. If the authored DVD folders play OK on the computer before burning....I'd blame TDK.
Also use ImgBurn to burn. It is THE ONLY burner for DVD.

If you buy any DL media except Verbatim you have wasted your money. You're stuck with the TDK discs for now so use ImgBurn and burn at 4x and you may be able to at least get through the pack without too many problems. I have no idea how TAW4 can determine the point of layer breaks. ImgBurn has an intelligent way to do it but you can also use PgcEdit to set it manually if you want to spend a few minutes on it prior to burning.

Thanks for the replies.

Since my post I used ImgBurn to create an ISO file of my DVD folder created from TAW4 and then used ImgBurn to burn that ISO to DL DVD. I set the layer break in ImgBurn and burned at 4X and the disc seems to playback fine thru the layer break point.

I should have done some research prior to buying these DL TDK discs...they were on sale for a good price so I just picked some up blindly and figured I'd give them a shot in my first foray into DL burning. From now on, I will buy Verbatim.
