Layer Change - Blu-ray Forum

Just wondered - if a film uses both layers on a dual layer BR disc, does that mean there will be a layer change pause, as there is with dual layer DVDs?

Physically there will be an interuption in the flow of data - however it's unlikely to impact your movie viewing pleasure.
I think the maximum for ROM per layer is 27GB. Even at 20+GB Very few movies if any will use up all that. Hopefully the size of buffers will increase - enough to cover the time to pick up the data stream (just in case).
The way the drive is laid out is going to be more like a computers hard disk than a single track (if my memory is correct - someone will correct me if I'm wrong). With careful authoring this delay can be drastically reduced by placing data in the same geographic reigon on the other layer.

Sony has already promised seemless layer changes on BD. So no, you shouldn't even be able to detect an interruption during a layer change.
