I make backup SVCD's of my DVD's on my computer which play beautifully there, then I take them to the living room, insert them in my DVD-5800 and, while the audio and video is beautiful, the lip synchronization is so far off as to be unbearable to watch.

I've scoured my instruction book and this site but, can't find any help. What adjustments can I make to the DVD-5800 to make my SVCD's play correctly?

Thank you.
