I am using Pansonic's own DVD-Ram discs in my ES20D but in the last week it has started to lose time on them.

What I mean is that when a blank disc should have 2hrs standard play available, after using it once to record then deleting the program, I am left with sometimes as little as 1hr 46mins left!

I tried formatting the discs several times. Sometimes that will gain a few minutes but never back up to the 2hrs.

Anyone else come across this, or know if it's a disc or a hardware fault?
