LIGHTNING UK!

Why are you using file splitting? ImgBurn makes an MDS file when an image is split into multiple parts (note that the individual bits are of no use on their own) or when it's under 1GB in size (so you can mount the MDS in DAEMON Tools and have it emulate a DVD rather than a CD). As for the ISO folder, I've no idea. If it isn't actually in the image file like that, it must be something WinRAR is doing.

You'd want the ones with the MCC media code. Not the 'value' stuff that could use a different media code.

Playing a disc doesn't necessarily cause the player to read every sector on the disc, verifying does. Playback often doesn't care about the odd unreadable sector either (it skips them), verifying does. If your drive keeps producing unreadable discs, either buy different disc that the drive does a better job of burning or try adjusting the write speed down to 8x.

You can't 'roll back' discs unless they're rewritable - and even then it's only cd-RW and DVD-RW that need to be erased before you can try writing to them again.

The drive is just reporting a 'Write Error'. There's nothing I can do about that I'm afraid, it's purely an issue between your drive and the media. Try burning at 4x rather than MAX (6x).

ImgBurn treats DVD-RAM no differently to any normal disc. If you want to use it as a giant floppy disc then you'll have to use the OS to handle that sort of thing (and put up with the speed).

That line in your first post works fine for me. I don't use UAC though.

That's a LiteOn drive and the program should handle it automatically. Burn a DVD+R / DVD+R DL and see what the booktype is listed as when it goes onto the verification stage.

I was talking more about the drivers for the SATA controller. As yours appears to be running in 'RAID' mode I can only assume it's an AMD board or something? Intel ones don't normally present themselves in that way. I/O errors are errors the drive reports when attempting to burn to the media - so they're normally caused by your drive not liking the discs you're using (or at least not liking them at the speed you're burning them at).

I'm not seeing errors in that, just a ton of buffering issues where your source drive is unable to keep up with the writer. Lockups are usually driver related.

No, you can't use ImgBurn to convert them... you'd have to use the programs mentioned (or similar).

They're video files yeah? Use DVD Flick / ConvertXtoDVD to make a set of DVD Video compliant folders/files and then burn those.

Yes, you'd need to use another program to make your DVD Video compliant folders/files first.

ImgBurn Portable is nothing to do with me and that error is nothing to do with me. Actually, neither of the errors you mention are.

This doesn't sound related to ImgBurn, it just burns what you give it to a disc.

Every make of drive is different and I'd basically just be guessing at what the official flashers do. Why risk bricking someone's drive?!

Hmmm... weird!

It should do it automatically for LG drives.

Not with ImgBurn, no. Try bd rebuilder or DVD Fab.

where are you talking about exactly? I'd have expected the replace file dialog boxes to already list the size of the existing destination file.

The cue is an 'image file', so you burn it using Write mode (write image file to disc).

Assuming ImgBurn reports a 'Write Speed - Effective: ....' faster than 8x in the Log window (and the buffers are all at 100% during the burn), it must be something the drive is doing internally.

If it was a USB limitation, it would limit both the read AND write speed.

It doesn't change anything, it just adds itself to the list of options.

That's a Windows dialog box and nothing to do with ImgBurn really. It activates it and then waits for it to terminate and return the file name you selected. I have no idea why it would be freezing for a while, sorry. ImgBurn uses *.ISO when the filename you select (or the generated one) is all caps. Otherwise it uses *.iso. Windows isn't case sensitive so it doesn't really matter either way.
