DVD Architect Pro 6.0 Disc Space % Indicator

Jep wrote on 12/26/2019, 6:40 PM

I use DVD Architect Pro 6.0 to create Bluray discs. In the bottom right hand corner of DVDA there is an indicator showing the percentage of disc space used by the project. If the disc space used goes above 94% DVDA will create the ISO image, but when it comes to the burn stage I will get an error message saying there is not enough space on the Bluray disc I'm burning to.

So, I'm wondering why I can't use more than 94% as shown by the indicator?

I had a look at the "Internal" settings. There is an item with a field name of "Max safe DVD space %" and it is set to a value of 95.00000000. Does anybody know if that has something to do with it, and if I changed the value to say 99.00000000, would that allow me to squeeze a little bit more space out of my discs?

It is not a major issue - but if anyone has any insights I'd be very grateful to hear them.

TIA

What size is the iso file according to Windows? A 25 GB BR disc holds 23.3 gb in computer language. If it's under that it should burn. Try burning outside of DVDA with burning software such as Nero, or free ImgBurn.

Thanks for the suggestion Eric. I had a DVDA project which produced an ISO of 22.5 GB according to Windows ( or 23,652,864 KB to be exact). DVDA wouldn't burn it giving a popup saying there was not enough space on my BDRE disc. I tried adjusting the "Max safe DVD space" to 98.00000000 in DVDA preferencs but it still wouldn't burn.

However your post triggered a faint memory that Windows could burn ISOs' direct to disc without any third party software. So after a little hunting around I found the "Burn to disc" icon under the "Share" tab in Windows explorer. I selected my ISO and clicked on the icon and Windows started burning the disc immediately. I've only done a quick scan through the finished disc, but it appears to be perfect from what I can see.

But - here's the surprising thing. Windows burned the entire disc in a matter of 3 minutes or so. DVDA would take over an hour to run through the burn stage on a project of that size!!! That is an amazing difference in time, and I'm wondering if I'm missing something. Maybe the shorter Windows burn time results in less reliable discs or something. Don't know, but would like to hear any opinions.

For the moment I'm only going to use DVDA to prepare my ISO files and then burn them to disc with Windows. I'll see what happens.

Thanks again.

Three minutes is very quick for a fullish disc. Maybe different burn speed but the difference between that and an hour is substantial.

Maybe DVD A needed to recompress if/when you finally got it to burn?

From memory a full BR disc does take a while to burn after all it's 25gb.

Yep. In fact I'd say spectacular. So much so that I decided to test it out in some detail and weirdness ensued!!!

I used DVDA to create and ISO file from a project that indicated disc space used at 87%. The resulting ISO file was 20.9 GB. I then burnt it to BDRE disc twice - once with DVDA and once with Windows Burn to Disc.

DVDA completed the burn in 1 hour 29 minutes. Windows took just over 2 hours 15 minutes. WTF!!! I tried again with Windows Burn to Disc, but using a brand new BDRE disc as I thought perhaps the disc I used in my initial test may have been faulty - but that made no difference.

I'm bemused to say the least. Yesterday I sat and watched as Windows burned a full BDRE disc in about 3 minutes, 5 at the very most. Now it is taking over 2 hours. Just don't understand what is happening. Weird.

@Jep To burn a full 25gb BR disc at 3-5 Mins you'd need a burn speed of 24X, according to my calculations. I don't think BR discs that burn at that speed are available, certainly not BD-RE. What speed are your discs?

I'm using BDRE. Max write speed is 2X for BDRE.

So there's no way Windows could have burnt the disc in 3-5 minutes! Have you tried playing it?

It might have burnt a directory or something, but not 20gigs of video.
