I got this reply from Panasonic:
In response, I would explain that pausing live TV is a feature available on
a Sky + box. It is not, regrettably, available on the DMR-EX95EB DVD
recorder.
However, the unit does have the Time Slip feature, which allows you to
watch a programme while recording it. You can choose how far back in
minutes that you want to begin watching the ongoing recording. For example,
if you have recorded the first ten minutes of a film and decide therefore
to start watching it, you can start watching the film from the beginning
while continuing to record. Time slip can only be activated ten minutes
after the recording starts therefore it is not live.
Curious, as this machine has both DVD-RAM and a hard disk.
