Well, yes, Slax 7.0.5, just like standard Porteus 2.0-rc1, offers two choices to play videos: Gnome Mplayer and SMplayer. However, as I said, in Slax you can't play Gnome Mplayer out of the box (I thought it was done on purpose but perhaps that's a Slax bug I've come across which results in the error message as reported earlier here). Anyway, I've done per your suggestion and have enabled cache for 2000 KB in Gnome Mplayer within standard Porteus 2.0-rc1 on the usual laptop featuring 1.3 GHz processor and 768 MB of RAM. Enabling cache did not make any perceivable difference at all on my system.
Please note that (also stated in my previous post) I haven't been able to duplicate the situation where sound would get out of synch with images and then slowly die out...... Instead, what's been consistently happening lately is that, with a few DVDs, there's no sound at all in Gnome Mplayer within Porteus and it also has a few glitches, like a funny fading out of colors during the first track before the actual movie, and images breaking down......it feels like something is missing to make it run properly.....however, this has nothing to do with enabling/not enabling cache on my system. Most of the problem movies that played without sound are foreign ones and some of them ripped off, but this has happened also with a few original DVDs made for the US market. Again, this malfunctioning is taking place only in Gnome Mplayer from Porteus 2.0-rc1 and it is not happening at all with Gnome Mplayer from Slax 7.0.5 (latest version) and from Slax 6.1.2. It is also NOT happening with Smplayer from Porteus 2.0-rc1. I have no idea why this is so, but I have tested repeatedly last evening and now in the middle of the night (it is now 2:50 in the morning here).
could you make a quick test for me and check if enabling 2MB cache bufor in gnome mplayer would resolve audio/video sync problem?
As I just said, enabling 2MB cache in Gnome Mplayer did not make any difference. But please remember that the instances of the audio/video sync problem only occurred a few days ago and after that I haven't been able to duplicate them. It's puzzling, I know, as it is the same computer, same Porteus, same DVDs...... Hope it helps.
