Bought a New DVR-100

No where on the box does it say DVR-110D. How can I tell if its a DVR-100 or 110D, before I flash it. Is it on the Hardware somewhere?

They are all the same, equal drive.

Go to Pio us support site and download new firmware.

My 100 was a 110d also. the 100 just gives you nice software package and docs.
110d FW should work.
