The firmware upgrade will also enable the cloning of tapes
when recording from another HDV source, such as a GY-HD100U, GY-HD110U,
GY-HD250U or another BR-HD50U VTR.
Currently shipping JVC ProHD BR-HD50U VTRs have an "A"
indication on the product and do not require the upgrade.
Customers who don't wish to install the firmware themselves
have the option of sending their unit to JVC Service and Engineering to have
the firmware installed for a $75 fee.
