The DM 600 PVR is the same small size as the DM 500 but includes an IDE interface allowing to add an internal 2.5 in laptop-type hard disk drive. On the outside it adds an S-Video output connector and an analog modem port. It is built around the same IBM STBx25xx integrated controller, but features 32 MiB of flash and 96 MiB of RAM, of which 64 MiB are user-accessible. It is possible to change the tuner module, selecting between Satellite, Terrestrial and Cable versions.
Its a far superior box due to the extra flash and Ram .
