What is difference between Sony DVM 60PR and Sony DVM 60PRL tape? I have been using the PRL tapes for a couple of years now and they are great and inexpensive. They are the ones that come in the blue wrapper (at least in the USA),

While looking online I saw for about the same price Sony tapes with the PR suffix rather than PRL. The pic showed an orange wrapper.

IMO the same tape will be in both .. manufacturers regularly change packaging to keep you interested.
Cheers.
