I have a weird problem with my notebook (Core 2 duo T7400, Radeon 2400HD Realtek ALC660 and WINXP)
If I play any video vith the last VLC (release 1.0.1) the sound appears running irregularly, with clicks, brief out of sinc, silence and so on. (CPU usage 22%)
Running VLC 0.8.6f I see no problem.
Because I have several hard drives bootable, I tested it on Vista (no problem) and on another XP with almost no software installed (same trouble)
Any clue?
