[Looser]

when i play vob files there are 5 seconds of good play and then the stream went not smooth for about 2/3 seconds then ti goes well for others 5 secs. ecc... looping.
i copyed vob files to xbox hd to remove the possibility of network problems (i use relax) but the problem persist.
if i play avi files (divx 5.11) the problem disapear.
what the hell may be?

thanks
looser
