Forgive me if this has been anwered before, but I've searched and found no answer to the issue:

I've noticed that video playback from image files (both bin/cue and iso) causes sound skipping every few seconds, as long as I set cycles=max. I've tried several games, all with the same result: Wing Commander 3 & 4, Tomb Raider and Warcraft 2, along with official DOSBox 0.74 as well as ykhwong's latest SVN build (20130205), and a vanilla dosbox.conf (generated with "config -writeconf").

So far, I found only two solutions:
1. use a fixed cycle setting low enough so it doesn't hit cpu limit (e.g. 10000), or
2. set prebuffer=50 (or above).

Both solutions are bad performance-wise: quite obviously when it comes to fixed cycles, but the larger prebuffer also has a major impact, at least on weaker systems (In my case an Intel Atom netbook @1.6 GHz, a Celeron notebook @1.7 GHz, and a Core2Duo notebook @2.26 GHz). One is running Windows XP, the other two Windows 8.
I can provide further system specs, but I don't think the problem's hardware related, as it's the same on a variety of different systems, even on the various Android ports (all based on 0.74).

Has anyone experienced the same, and is there another fix? Or am I missing something obvious?

Thanks in advance!
