I'm having problems lately with burning CDs with 48x speed. Both DiscJuggler and Alcohol 120% will always suffer from an empty buffer and pause burning (burn-proof);
INSERT INTO `portal_posts_text` VALUES
and then either continue with max speed or sometimes with only 24x.

Can anyone confirm these problems? It can definitely not be my hardware as I haven't changed anything lately and I was able to perfectly burn with max speed (48x) from the first to the last sector some time ago...

Now I get buffer underruns over and over when trying to copy on-the-fly, and sometimes during the burning process from HDD. If not when burning from HDD, DiscJuggler will always have problems when finishing the disc - while finishing it will pause burning like when it has a buffer underrun.

My system specs:

AMD Athlon XP 1800+
ASUS A7V333 (VIA KT333)
512MB RAM 266MHz
Seagate ST380021A (80GB 7200rpm) primary master
Toshiba SD-M1612 secondary master
Lite-On LTR48125W secondary slave

Windows XP Pro SP1
VIA Hyperion 4in1 v4.45v (all DMA enabled)

No firewall/antivirus installed

Hope I haven't forgotten anything...
