When previewing DVDs I am downloading, the sound is about 2 seconds behind the pictures. This is new. Only been happening for last 2 weeks and affects all DVD downloads.

Any advice gratefully received!

Codecs issue on your computer. Update them since new version codecs come out not infrequently.

A back up player is a wise idea btw CODECs list for Movies/Audio/ Alternate players / Video help forums, especially one that has built-in codecs.

Lord of the Rings,

Much obliged, I'll check it out.
