Mini Dv Tape Differences...??!
 

Anybody out there know their Mini DV tapes by any chance...??

I've been using Panasonic DV tapes for my Xl1s and XM2 for some time.
They were boxed as:
Panasonic AY-DVM60EF (DVC 60's)

I've now bought through another dealer some:
Panasonic ME-DVM60 (DVC 60's)

Am I being a bit picky...but are these essentially the same tape (and therefore safe to use in my cameras as I want to keep the same brand/manufacturer), or is there a significance to the AY pre fix?

Any ideas>?

Thanks

Perhaps it is best to contact Panasonic with this question? I doubt
anyone outside Pana knows exactly what the differences are....
