Are you in write mode?

Select page two in that General tab and you'll see the setting.

Perhaps you have some tool in the lap top that deletes the last placce where you where when you added files/folders?

My impression is that it's not enabled by default.

Not the best media. I would suggest you try with some better media like Verbatim +R DL. My own Samsung is not very good with RITEK-S04-66 based media.

Most modern ones supports it. My cheap "non brands" also works and they are some years old. You'll never find in any manual that is shipped with a player if it supports the option or not. Burn a DL disc with the option enabled and the layer break in the middle of a video titelset and take the disc to the shop and watch what's happens when it plays at the layer break.

Can you post a log from one of your burns? You find old logs here: Main Menu -> Help -> ImgBurn Logs

It's possible to add menus in DVDFlick.

You need to convert them to DVD Video format first if your stand alone player can't play .avi files directly. Here is one free program that can do the task + it will use ImgBurn for the burning part. http://www.dvdflick.net/

You can't burn at 2.4x, your drive only sees the quoted speeds. Try faster burning and cleaning the drive. Well that makes perfect sense. I'll try to burn on 4x speed. You already tried with 4x and that was the failure you posted last time.

What model of burner do you have?

If you select Read mode and put in a blanc disc - do you still see the 'Unknown' things?

In my opinion the 1x write (or write as slow as you drive can perform) suggestings that you can see on various boards is the joke of the century. It might have been true in the early days of DVD burning when the burner couldn't burn faster than 4-8x. I would also say that the Optiarc is a nicer burner than your Lite-On with DL media. My suggestion to know if the discs are burned good or not (they can be a joke even if you don't get any error messages in ImgBurn) is to do a quality scan of the burned discs in a program like Nero DiscSpeed, DVDInfoPro or Opti Drive Control. DVDInfoPro has a 30 days demo period. If you use this program; select 'Block' and set the speed to 4x in the 'Scan' option. Use your Lite-On for this purpose. This would inform you if the burn is good or not. Post the image of the scan and we can help you interpret the scan.

What error message in ImgBurn do you get when you burn those?

The media is a hit and miss especially with older drives, so I would say it's the media that is causing your issues.

If your stand alone player supports the seam less option - it doesn't matter which one you select as you never will notice the layer switch.

Any chance you can add some logs of the different scenarios?

I wish all of you a Happy New Year!

The issue is that Optiarc decided that the firmware/burner shouldn't support any lower write speeds than 4x for that media code. There is also a 1.03 version of the firmware for that drive. http://www.firmwarehq.com/Optiarc/AD-7240S/files.html Why is it so important to burn at 1x or 2x?

They are nice scanners. For burning they can be nice (even if there are nicer ones IMHO), but you can face the not so nice error 'PMA update failure' if you use +R media. They do have a nice little USB attached mini drive (burner) that doesn't take to much space if you just want a scanner.

Check so that it's not the defragger that starts at the same time as your burn.

OT. Did two scans of the same discs in one Pioneer and one Lite-On. Very different values.

The interesting stuff usually happens at the end of the disc. Use the 'Discovery mode' and select all sectors. I use these settings: PIF = Block Speed = 4x

Under 'Scan'.

Perhaps the hard disk is stuck in PIO mode instead of DMA mode. http://club.myce.com/f61/troubleshooting-enabling-checking-dma-windows-vista-xp-2000-me-9x-101616/
