#53 I/O-Error while burning (bufferunderrun)

Dr. Tom Silent

I've been using CDRDAO under TSCV for a reasonable
time without any problems.
- OS: Win XP Home
- CPU: Athlon XP 1700+

Now - I'm quite sure :) that I did not change
configuration of my PC - I don't succeed in burning a
SVCD any more. The log of TSCV is as follows
(VCDEasy is the same):

Starting CDRDAO Burning process...

Cdrdao version 1.1.5 - (C) Andreas Mueller

Additional Info:
- CDRW is working / CDR not (strange?!)
- Burning of audio- /data-CD with WinOnCD is ok
- Direct-CD burning is ok
==> so probably burner is OK?

Do you have an idea?

Thanks and so long, Thomas

    Hello Thomas

    I have the same problem, I'm using MAC OSX 10.2 on a G4 Titanium,
    Freebsd, next is my error log, btw I found out that this only happened
    when I'm doing an Overburn CD, all others CD's works fine, so I think
    the driver is allowing to do the Overburn procces well.
