LIGHTNING UK!

Do you have access to another computer / drive to try and read the disc in that instead? Is it a disc you've burnt in the past? If so, how long ago? What condition is the disc in? Make sure it's clean.

On some OS's, yes. They changed the way it works a bit in the newer OS's though and so an updated version of ImgBurn would be required for those. It's purely cosmetic though, so don't worry about it too much.

Build mode Set the output to image file.

No, not via CMD line, this is in the program itself. Go into Build mode and then select the 'Advanced' tab on the right, followed by the 'Media' one. Change the Single Layer - Profile to 'Custom' and then enter a larger number. Maybe just copy the value from the double layer DVD+R DL one (i.e. 4173824).

Well, I say that.... if you just want an ISO for playback via a media player rather than for burning to disc (basically anything where the layer break isn't important), you can change the size of single layer media to something larger than DVD9 and it won't prompt you.

In a word, no.

Post the log from ImgBurn please. Copy and paste it all from the log window when you think it's stuck

Turn off (uncheck) the following... Tools -> Settings -> General -> Page 1 -> Display Warnings -> Underburning

It looks like it had trouble writing to the disc - the drive reported a Write error. Maybe it did a better job with power calibration the 2nd time around and so managed to burn it ok. You were lucky the first attempt didn’t render it useless

That's not something you do in ImgBurn. You need some sort of authoring program if you want to add multiple video files along with a menu where you can pick which one plays. Something like ConvertXtoDVD might work here.

The program queries the drive's current setting and that's what is being displayed in the log when you burn. It doesn't actively request that the drive changes the booktype to DVD-ROM if the setting you've mentioned isn't checked.... but it also won't then tell it NOT to booktype to DVD-ROM if that's what it has already defaulted to doing. So.... go into the booktype changing tool/feature and tell the drive that you don't want it to booktype the disc to DVD-ROM.

Add the drive letter (i.e. D:\) of your optical drive to the source box. Set the output to 'image file', fill out the destination file name and press the start button.

Probably from CloneDVD then... I'm not really sure, it was forever ago as I'm pretty sure they were used in DVD Decrypter too.

And you're changing it in Tools -> Settings -> Events -> On Startup -> Check For Program Update? (setting it to 'Never') If you want to do it in regedit, it's the 'EVENTS_CheckForProgramUpdate' setting in the key dbminter mentioned. Set it to 0.

It does 'stick', so maybe it's something to do with how it's being called. Is another program firing ImgBurn up automatically? They often tell the program not to save the settings on exit or provide it with an ini file to control the configuration.

The program is at the mercy of your machine as a whole. If your machine stops processing the I/O requests it tries to send to the drive, it will appear to be frozen - it’s actually just waiting for a response to something. So the problem could be something related to a communication issue with the drive. Load the program up, go into write mode, right click the drive selection box and select ‘family tree’. Close the prompt that comes up and then copy + paste everything from the Log window please.

ImgBurn burns as-is, so your issue is with whatever you've burnt and the way your playback device handles it.

That label will show up in Explorer on your computer. A standalone player may or may not read / display it.

There are free tools out there that will convert your files to DVD Video format. Then it's a simple case of dropping the VIDEO_TS folder into ImgBurn and burning. 'AVStoDVD' and 'DVD Flick' spring to mind.

Think of an ISO like a box.... that's all it is. You put things in it, but they don't change. So if you put MKV/MP4 files in an ISO 'box', when you look inside the ISO 'box', you still have the same MKV/MP4 files. Either you used to start off with compliant DVD Video (VIDEO_TS) stuff (and not MP4/MKV) or you used another program to convert to DVD Video format (VIDEO_TS) and then used ImgBurn for the burning part. Lots of freeware conversion tools can automatically call upon ImgBurn for the burning phase.

ImgBurn burn as-is, it always has done. So if you feed it MP4 / MKV files, that's what you'll end up with on the disc. If your play needs proper DVD Video discs (ones with the VIDEO_TS folder and usual set of files), you'll need to convert your MP4 / MKV files into that format before then burning the VIDEO_TS folder. You must have been using different software (or an additional piece of software) on your older PC and have started skipping a step on your new one.

Don't block it at your firewall. Let it through or turn off the 'check for updates' option.

No, I just downloaded it and checked it for myself.

Mirror 7's download still matches the CRC/MD5/SHA1 values posted.
