An alternative Tivo-like DVR that was introduced in 1999. Hardware was typically made by Panasonic although a few other brands existed also.

ReplayTV had a few defining features, one of which was the ability to share shows between two compatible DVR units, providing both had ethernet sockets. Another feature was the ability to skip adverts completely with the touch of a button. Naturally the TV industry hated the idea and ReplayTV (SonicBlue) was sued because copyright matters more than human rights.

Like Tivo a separate subscription was required for your DVR to receive EPG data

Main Menu

To begin using ReplayTV the best place to start is the Main Menu.  To access the Main Menu, simply hit the menu button at the bottom of the ReplayTV Remote Control.  The main menu screen is available without leaving the current channel.  It pops up as a small section at the bottom of TV screen and presents the following options, most of which are also available directly on the remote control.

  • ReplayTV Guide – This shows the ReplayTV Channels you have created.
  • ReplayTV Zones – ReplayTV Zones are common themes of shows organized together.
  • Channel Guide – Shows a grid-style TV guide for selecting something to watch.
  • Messages – Shows any messages you have received.
  • Find Shows – Search tool to help you find something to watch or record.
  • Setup  – Configuration of the ReplayTV TV Reciever.

ReplayTV’s channel guide is pretty conventional.  It is a Grid style Guide that shows 6 channels down and 1 1/2 hours across.  It also shows the currently selected channel, title, time, and description of the show. One very cool feature is the way it shows your position in the selected show. Rather than showing how much time is remaining, which is pretty useless information,  it tells you how far into the show you are.  For example, on a thirty-minute show that has 10 minutes left, the ReplayTV will say 20 minutes in progress. This is great if what you want to know is how much you have missed.

Rather than organizing the recorded shows into a simple list, ReplayTV decided to use a concept similar to a grid-style guide to organizing the recorded shows. When you select shows to record, whether they are setup to record based on a theme or setup to record a specific show, they appear as a channel in the ReplayTV Guide.

ReplayZones are logical groupings of shows.  For instance, there is a ReplayTV zone for NBC and Cartoon Network, which lets you explore some of the best shows on the channel.  There are also zones for Movies, Comedies and ReplayTV Picks.  The ReplayTV Movies zone shows various movies that are coming to a channel near you organized by category  ReplayTV Sitcoms, shows you comedies organized by audience, such as 17 and over.  Finally, ReplayPicks lists a random show in various categories that you might want to watch.

Also in the ReplayZones screen are two other options, Search and Create a Theme.  Search allows you to search for shows based on a large number of pre-created groupings, such as ratings, or genres.  The Create a Theme option allows you to specify your own keyword searches to use for looking up shows that will be recorded.  You can also specify if the keyword will be compared against actors, directors, titles or part of the description. These themes show up in your ReplayGuide as channels and are great for creating themes for related shows when the title isn’t the same. 

As with all PTV Receivers, there are certain features that separate these boxes from VCR’s   And ReplayTV is no exception. For instance you can pause, rewind and fast forward Live TV.   When you hit pause the box will begin recording to the hard drive.  This happens regardless of whether you are watching Satellite or Cable programs.  Also, whenever you change the channel,  ReplayTV immediately starts recording the new channel.  This means that you can rewind at anytime to the point where you switched to the current channel.  You can also jump backward or forward to live television at the touch of a button. 

Further Information

The Replay Zones menu was redesigned to a more flat and simple appearance

A slideshow composed of various photos can be played back

The Setup menu

Video output settings, The RF output channel can be changed, along with the VGA output standard

Many early HDTV TV’s used either VGA or DVI to display the HD signal, as HDMI was not standardized at this point

Configuring slideshow settings for displaying photos

Multiple ReplayTV units can exist on a network, and a unique name can be used to identify an individual box

Quality settings can be changed, as the DVR captures analog video from its composite input

Parental control settings

Settings can be applied depending on the age rating

Manually setting an IP address

A controversial feature allowing you to skip advert breaks entirely. Other DVRs like Tivo require you to manually fast forward.

Playing back a show, which gives the option to archive to a VCR

Transferring shows to another DVR over the network, I bet the networks would have loved that.

A look at the Panasonic TU-DSB40

Panasonic were one of the major manufactures of Sky Digibox’s, and were considered to be one of the more reliable makes in terms of reliability and performance.

The front panel is typical of the average Sky box of the era, 4 led lights followed by 9 front panel buttons along with two card slots.

Lifting the Lid

A very clean design, similar to the 2500S5

On the left you can see the main CPU and MPEG2 decoder, seems to be a custom Panasonic MN2 processor (MN2WS0002AD). Whilst I’ve not been able to find a lot of detail on it online, It’s a lot faster than the ST 5512 found in the Pace 2500S5

Not sure about the Panasonic chip towards the bottom, the MN7D022B3M, nothing much turns up online. Not much can be found with the Conexant chip either (SMARTSCM/336 CX88168-12) however one MAME driver source page has it down as a modem

Second card slot

Main central processor MN2WS0002AD, Looks like it’s missing a heatsink, or maybe Panasonic figured it didn’t need one. Most likely Sky winged about the price so Panasonic had to cut corners. Still the box feels cool to the touch when in use.

Vs Pace 2500S5

Vs Pace Di4000N


The DSB40 comes from the same generation of digibox as my 2500S5, yet it feels so much faster in operation thanks to its processor. I’m not sure why Pace held onto the St5512 for so long when over digibox’s were moving onto more capable processors. Unfortunately I’m not able to find any further information regarding Panasonic’s MN2 chips that they used, only that they were used for Directv and OpenCable boxes also, and they were mostly MIPS based designed like the NEC EMMA used on some digibox’s.

Then again this box is running older software, maybe the later versions were more demanding?

The only major issue the the telephone cable connector, once you insert the wire, its suck to the digibox and cannot be removed without removing the back panel. I’m not sure why this is, if the connecter was mismatched for the case or maybe it was a cost saving design.
