This applies to pre-recorded, genuine, shop-bought DVDs as well as home-recorded DVDs. At the start of each chapter, there is a brief pause in the action. It is especially noticeable when there's a gap in the otherwise continuous soundtrack. I used to think it was just the odd disc, but no, it really is every one. I've looked through all the settings on the DVD player, but can't see anything obvious to change. Any ideas very welcome. Many thanks, Mick
