The DMR-PWT420 is able to record two digital broadcasts at the same time thanks to integrated twin HD tuners, so users can simultaneously watch and record a digital broadcast.

The DMR-PWT420 is equipped with DLNA server/client functionality. By connecting to a LAN and using a compatible DLNA client device, recorded programmes and AVCHD and JPEG data archived on DIGA's HDD can be enjoyed in a separate room. In addition, WMV, AVCHD, JPEG, and MP3 data can be played on DIGA from a personal computer with a DLNA server function.

The EPG screen also shows the programme presently being watched in a small window, so the user can continue to watch it while searching through the EPG for another programme.

It easily connects to Netflix, BBC iPlayer, Acetrax, Dailymotion, YouTube, Viewster, Facebook, CineTrailer and euronews for an even wider variety of Internet content from to expand home entertainment with family and friends right from the comfort of the living room sofa.

The DMR-PWT420 supports a USB-compatible external HDD, so collections of content recorded onto DIGA can be moved over to the external HDD. Further, the content that has been moved to the external HDD can be played directly via DIGA.
