Try some newer media. It appears that low speed RW media may not be supported by all drives.
I have some “very old” DVD+RW & DVD-RW discs that I use when burning movies that I only plan on watching once and then erase. I “never” have an issue during the burning process and they always play great on my stand-alone DVD player. On my “old” windows xp Dell computer, I could burn my Verbatim DVD-Rs at 4x. Verbatim DVD+R, MCC, part number 95098. It was extremely rare that there was ever a 'burning' issue, with these discs. Before I knew better, I used to buy the cheapest blank media that I could find, and they usually worked just fine.
Now, new Dell desktop pc, year and a half old, originally windows 8.1, but now windows 10. Still using those “old” 'RW's without issue. But now, using the same Verbatim DVD's, the 'slowest' burn speed allowed on this “new” pc dvd burner is 6x, and, from time to time, I get these failure to start the burn process. This might happen 2, 3, 4, once 7 times, before it finally “starts” to burn. The “finished” DVD's seem to play fine on the stand-alone DVD player. I have now set the burn speed to 8x, but the issue still shows up. I usually burn all projects with the ImgBurn program. Sometimes the 'read/verify' part fails (didn't have this issue before) and I have to abort the process and start anew with another DVD disc.
Windows 10 Home – version 1511 (OS Build 10586.71) / Intel® Pentium® CPU G3220 @ 3.00GHz / Installed memory: 8.00 GB / 64-bit Operating System x64-based processor
FYI, I use a DVD disc cleaner every once in a while. I don't use the computer while running these projects. Task Manager shows only around 25% CPU & less than 30% memory.
ImgBurn shows: Destination Media Supported Write Speeds: 6x, 8x, 12x, 16x. “No” 4x
FYI, since I was using the convertxtodvd program, I began by going to their forum. Thinking it had something to do with their program. After a “lot” of tests, they suggested that I get a new 'DVD disc burner'. Called Dell, they took over my computer and could find nothing wrong with my 'burner', but, on my insistence, they sent me a new burner, which I installed. Frankly, I didn't notice any difference.
So, that was about 'six' months ago, so I thought I would check with the ImgBurn forum. No luck there, they also suggested I get a new DVD burner.
I haven't tried a different 'software' burning program, so maybe I can try that “cheaper” option first. Even though I have been using ImgBurn, since like forever. I have been 'burning' DVD's for at least 10 years.
The point I am trying to make, is that if I “can” burn DVD-RW's at 2.4x or 4x and the results “are” “perfect” every single time, without fail. No 'time out' or read / verify issues. That would seem to indicate that there is nothing wrong with the DVD disc burner. I have to also conclude that there must be nothing wrong with the 'convertxtodvd' program that I am using because everything starts with this program and then I use ImgBurn to burn the project.
Just trying to resolve a long running issue.
Thanks for reading this long post.
