DSR 704 software version upgrade

[hopware]

Hello all, I have a DSR 704 currently running software version 3.1 something. I went cellular about 2 years ago, dumping my land line, therefore no software updates. I am going to upgrade the HD, and I was wondering if there are any useful features / advantages found in later software. Anyone know of a link that explains the differences between the different software versions? Thanks

The major changes with the 6.2 software is speed and grouping (aka folders). The upgrade with worth it just for the speed and folders are the icing on the cake.

They can also be hacked to add MRV and HMO which were previously unavailable with 3.1.x.
