DVD overburning. Is it possible?

[[_chef_]]

Hard to say, 40mb should be possible without BIG problems with most drives (readers).
With Plextors, you can overburn some DVD+R media up to nearly 5000mb!!! But that is just geek'ness.

[mats.hogberg]

OK. So - some part of a percent extra without BIG problems...

But its not worth the trouble.
I would either use DL or shrink the content a bit........

4.6MB is a typo for 4.6GB, in my educated guess. Hence answers about not burning 4.6GB. The limit is 4.38GB and for good reason.

Official NTSC specs don't call for MP2, but official PAL specs do. There is nothing limiting NTSC from adding MP2, but nothing specifically supporting it. On the other hand, there is a limit to how much data is to be put onto a DVD-Video disc. There is a minimum too, requiring long lead-outs for small discs. The MP2 audio thing is an aspect of the MPEG decoders, while the disc size is limited by other factors. So you cannot compare them.

I don't understand the sudden stupidity I've seen on this site lately. Either do things correctly or don't do them at all. Quit screwing up discs for no good reason. Sure as hell don't suggest others join in on your harebrained schemes.

You should run for President of the US. You have about as much intellectual curiosity as George Bush.

The only reason to over burn is for copy protection. If you just want to put more on the DVD then shrink more.

So I'm really late, by years, but a general update:

1) Overburning can be done, on + and - media despite what you may read elsewhere

2) If your burner supports overburning, your burner will probably read the overburnt disc

3) Overburnt DVD VIDEO discs will probably play in 60-75% of standalone players, and upwards of 90% of computer drives; depending on WHO YOUR READ the numbers from. Overburnt data discs are almost always readable by computer drives

4) Overburning is ALWAYS risky, but good software (IMGBurn, Nero, ISOBuster...) allow for a true raw data verification. If it verifies good, then you're good. Period.

5) DVD specifications are there for a reason. It doesn't matter if you like the reasons or not. When you violate the specs, it's no longer that item. An overburnt DVD-Video disc is no longer a DVD-Video disc. It's an optical disc on a DVD that happens to use the DVD-Video file structure. That's not a bad thing on it's own, just accept that you are burning a modified, or hybrid disc.

6) I've had around 50/50 success with overburns on DVD + media, with better rates on Ty and Verb media, and lower on standard media. I've also found a 100% failure rate on Playo.
I've found that less than 20% of my - attempts work to any extent.

I never deliberately set out to do this, but wound up with that result inadvertently a couple times. It was a DVD that Explorer or my file manager program says is 4.6 or 4.7 -- maybe even a 4.8. At this point, I don't recall what program created them, or what the circumstances were. (A good guess would be Shrink-using-Nero, or ImgBurn.) These discs may be stuffed to the gills, but have played wherever I tried to play them -- not just in the computer.

How did you overburn a DVD-R disc??

How did you overburn a DVD-R disc??

Perhaps lostinlodos knows; I wasn't quite sure how it happened in my case. (See my post from June.)
However, I've burned things to single layer -R that totaled around 4.4 or so, which is supposed to be "full up." When ImgBurn calculated the size, it said something like 92 %. Ergo, there must be some extra capacity there beyond the official 4.46, or whatever it is. I understand that it may not be wise to use that additional space, but if it happens it is not automatically and for sure a disaster.

The program I've used on the RARE ocasion of overburning, with near total success is ISOBuster. A damaged-disc and image recovery tool. Well worth the small price in my book, it can recover anything, burn anything, and does bit-by-bit verification, from out to in and in reverse.

Beyond that for other software
, just set the advanced tab in Nero to allow for overburning supported media, and below that check the box that says allow burning on non-supported media.

For ImgBurn, use a totalling tool like nerodiscrescue (free) to find out the real size of the space on the disc. When burning the image, make sure you have enough space from the totalling program for the size of the image in bytes. Then check off the box when you go to burn the disc that tells you it's to big and asks if it should try anyway.


ALWAYS leave 6 kilobytes extra "real world" space for standalone DVD/CD players and audio disc players. That's the standard laser lead from what I picked up at AVS.

@seeker
Sometimes file sizes are just reported wrong. I've seen commercial DVDs that insist more than 9GB are on the disc. It's clearly an error.

O.K., then -- you would probably know the answer to this. I have a few non-standard, "oversize" CD blanks (90 - 100 min.s, vs. the normal 80 min.s) that I bought a few years ago at a computer show. Fina ? Fino ? I'm not sure of the brand, but believe it starts with an "F." Since these exist, I thought there might have been some "extended" length music CDs that have been released at different times by major record labels. [Edit: In fact, I have one live concert CD on my desk right now, from a major label. The liner notes say tracks were added back for this "special, extended edition" that they did not have room for on the original CD release, years ago. Clearly, they did this to have some renewed reason for sales of this title. But it's still all on one disc, and I don't think they played games with compression or bitrate to do this. How would I get a reliable capacity measurement for this disc ?]

IF that is true, why could this not also be the case for some commercial DVDs ? If such blanks exist and they are not too deviant from spec, Warner Bros. or whomever might have used them on occasion, and that could explain your anomalous readings ?

[lordsmurf]

No, not true for DVD, not as you suggest.

CD has a bit more leeway. I believe it's out-of-spec, too, when done. Not part of the book standards for Audio CD. Anyway, you can get 99-minute CD, both as press and burn. I forget the technical off-hand (would have to look it up), because people don't really do it that often -- most know how non-standard it is. Players often reject those discs, either entirely or partially.

And while you'd think a major label would stick to the specs, Sony and Disney don't always do it, among others. And they've been rightly lambasted for it, when caught.

[ocgw]

I had a CD-RW drive "back in the day" that warned that overburned discs could damage some drives

Is there any risk w/ DVD overburned discs?

[lordsmurf]

Yes, you can harm any drive by overburning.

What utter Bull$H!T...

For one thing, ISOBuster DOES NOT BURN DISCS. I love it as well as the next guy, but these claims are just lies.

For another, the LEADOUT on CDs and DVDs are different. On CDs, the spec says 90seconds @1x = 6750 sectors @ 2352bytes/sector > 15MB. Big difference from 6kB. On a DVD, it varies depending upon whether single or dual layer, etc. but the minimum is 1.0mm in width (whatever that amounts to...quite complicated) unless the total is less than 1GB, in which case it MUST pad out to 1GB to be compliant.

And those apps mentioned still don't really tell the whole story AFA disc space used...

Get real, and use a little science.
