I’m finding that some videos don’t play even though they are the same format as the ones that do play. The thing I notice is that the ones that don’t play are much larger than the ones that do. Is that the reason, i.e. too big. It seems unlikely to me but that seems to be the only reason I can see.
There are some ones that were created on the mac and some on the pc. Will that make a difference as to whether they are playable.
I’m still finding out about the machine. It’ is wonderful.
