Failed burn sessions w/ external recorder

vbimport
#1

Hi all,

I have written a small applet (in VB.NET), which uses NeroCOM to burn data from a magneto optical drive to DVD-R on the fly. The applet works fine on a machine with an internal recorder. On another machine with an external (USB) recorder, the burn sessions reproducibly fail every time after around 10 minutes. Why?

The relevant part, I think, from the nero log goes like this:

Does this help any of you NeroCOM gurus (alexp…)? If not I can elaborate on hardware, code, etc.
[full log burnmsg3.txt attached]

Thanks

Did you try decreasing the burn speed? This often helps with the external recorders.

Since you app works on a desktop machine, I’d suspect the reason for failure is not code related.

#3

Yes. 8X -> 4X. But I will further decrease burn speed. Thanks so far.

Just out of curiosity: Can’t you learn anything more specific from all those status/error codes in the log?

You could get a hint but the real intention is for the NeroAPI developers who can pinpoint the problem more accurately. There is a lot of info in the log that does not make sense to non-developers.<!-- / message -->

In case anyone’s interested: Problem solved.

The external USB recorder (Plextor PX-712UF) didn’t like the Verbatim DVD-Rs I used extensively for testing. It eats ANYTHING else, however (other manufacturers, DVD+Rs, etc.).

You can file that under “Murphy’s law”.
