The two apps are standalone, nothing gets deleted, uninstalled or overwritten. The bit you declined during the install of ImgBurn was nothing to do with the removal of DVD Decrypter, it was just to clean up your context menus so you didn't end up with 'Burn using DVD Decrypter' AND 'Burn using ImgBurn' when you right click an ISO image. Having both is pointless and as waste of space - hence why ImgBurn offers to clean it up for you. If the MDS file you have hasn't just been made by the 'Create DVD MDS File' option in the tools menu, the problem you're having with DL burns is that the images you're burning are from PTP DVDROM discs. You can't always burn such images onto an OTP disc because for OTP, Layer 0 must be bigger than (or the same size as) Layer 1. That is not true for PTP, where Layer 1 can be bigger than Layer 0. If the layerbreak position read from the MDS file is such that it cannot go on an OTP disc, the program has to attempt to move it. How well that works out is anyones guess! You should always use ImgBurn for DL burning now, it has other neat tricks that DVD Dec doesn't.

According to what I've read over at cdfreaks, BenQ forgot to add a write strategy for the MKM-001-00 discs into the firmware. That's why: 1) They only burn at 2.4x 2) They often fail to burn at all! Their next release should fix it.

I'd upgraded some of my UDF parsing code between dvd dec and imgburn. Only problem was, I forgot to update a certain variable with its replacement and it ended up making the 'file finding' function quit after reading info for about 39 files (which makes up 1 sector). As such, so long as the layerbreak position was in a file before number 39, it would be ok. After that, it wouldn't know those files existed and so program logic would prevent it from finding the layer break info in the IFO file.

Under newer OS's, I'm pretty sure Nero's ASPI DLL file is just a wrapper for SPTI - which is the default one in ImgBurn. As such, you'd need to install Adaptec's ASPI, ElbyCDIO or Patin-Couffin.

Well these errors are supposed to come directly from the drive. It seems very odd that some other program should be intercepting them and returning a bogus one! Have you tried using one of the other I/O interfaces? They may help you bypass whatever is causing the problem (if it's driver related). Otherwise I guess you have no choice but to rebuild again and test burn something before adding any programs back on. Maybe your IDE drivers (or lack of) are to blame... who knows!

Have you messed with the firmware on your drive? Power calibration errors are where the drive cant decided on the correct power lever to set the laser at for burning. That is most certainly a firmware issue. On the odd occassion it does get an ok (ish) level, it's still not good enough and that's why you're getting write errors. Stick with the official NEC firmware, at least then you can blame them when things go wrong!

Dragging this thread back up again.... Someone over at Doom9 had the same sort of problem. 5 mins later they'd emailed the 5mb chunk of ISO and 10 mins after that I'd found + fixed the problem. So I hadn't magically fixed it, but it has indeed been fixed now

[flame/sarcasm on] That would be the same as just burning normal files, as in 'data discs' as mentioned in a zillion other posts [flame/sarcasm off] Yes I hope this will indeed be possible one day.

That's unlikely to ever happen. Alcohol MDS/MDF type images need to be burnt with a program that supports burning protected images (in RAW mode). ImgBurn does not, and wont ever. If they're just basic ISO type images, it will already do it though.

Those might be new for 1.2.0.0 shamus

Ok, that's cool. Just to really point it out though... look at the 'NOTE:' line in the log. The actual data within the sector has compared just fine, it's the error correction stuff that's now different. Most drives totally ignore those bytes within the sector, on the fly when you burn - unless you burn in RAW mode (which I'm not). The drive then recalculates the data and burns the correct EDC/ECC data. So if you've not changed the image since it was first made, the program you used to create it hasn't done a very good job - because you drive is correcting what it has done! (That is a little weird though as it looks like you're using Microsoft's internal ISO building util!)

Hello and welcome to the forum ImgBurn can set the booktype stuff on your BenQ drive, just click the little 'book' type icon down the bottom right corner of the screen when in 'Write' mode. We had someone on here the other day saying the 1640 wasn't burning DL discs that well. Like you say, they are indeed expensive and the last thing I want to do is make you waste them! Some firmware versions will no doubt work better than others but in order to find the best, you need to find a lot of people who have already done the testing for you! As such, I'd recommend you take a look on the cdfreaks forums - they have one especially for BenQ drives - and see what people are posting about DL burns on a 1640. ImgBurn itself will burn DL images just fine though. All you need to worry about is your drive/firmware/media combo Oh and QSuite is quite a handy little tool, you might aswell install it.

Have you perhaps changed something - i.e. the volume label - since building that image? That would cause the error you're getting.

Sorry, it'll stay as paypal (and the very little used NoChex). Paypal is the one everyone knows about, and dare I say 'trusts' !

Ah ok cool How about on the original media you used.... MCC 004? Anyway, glad that one works at the right speed for ya.

Quite! I'm a very easy going chap really, but I have to draw the line when people come in and immediately start bitching about things that are totally out of my control - i.e. the demise of DVD Decrypter. Do these people think I'm happy about what's happened?! DVD Decrypter was my little baby!! The least painful way of dealing with the situation is just to not have ANY talk about DVD Decrypter - unless I determine it's a strictly 'writing' related problem and one that will have been copied over into ImgBurn - in which case, I'll fix it (within ImgBurn). If people want to chat DVD Decrypter, there are plenty of other forums they can use. This one is about ImgBurn. One day people will hopefully realise that!
