• The basic principle of the DVR has transformed the way people watch television. A DVR is a digital video recording device that is sometimes called a PVR, which means almost the same thing – personal video recorder. It is a consumer electronic device that is programmed with application software. This application software allows it to record video in digital format to different types of memory.

In this day and age, the average person has no need to schedule an entire evening around a favorite show. DVR owners have their digital video recorder settings on their device automatically set to record TV, videos, sports, and movies for later viewing. Most DVRs have a feature that lets you subscribe to shows; set the DVR once and never worry about missing another episode again, even if it changes times or days of the week.

The most common memory used in the DVR is the hard drive. Local DVR hard drives normally exceed their recording capacity. Video files such as sports, movies, TV shows, and other telecommunication programming are very large High-definition files stored to the DVR hard drive memory using the application software. At its most basic level, a DVR is really just a computer designed for a specific task. And just like any other computer, with the right screwdrivers, knowledge and tools, you can switch out components for new hardware.

Video files use up tons of storage space on the hard drive. The basic math depicts 80 to 180 hours of standard programming; or 20 hours of high-definition television programming memory space isn't enough. All DVR owners manage to fill their device's hard drive to capacity. Many DVRs will overwrite old programs in order to make room for new recordings, which means eventually losing the shows record for safe keeping, or the DVR will have to stop saving new shows.

Maintaining, repairing, recycling, refurbishing, or reusing Cisco Explorer DVR, (SA) Scientific Atlanta DVR, Motorola DVR, or any other set top cable/satellite box requires special security screwdrivers. These special security bits are available in this tool set. Unfortunately these tamper proof fasteners cannot be removed by traditional screwdrivers such as the common Phillips or slotted available at the local hardware brick and mortar. This particular security set contains each tamperproof driver bit necessary to get the job done.

There are 105 pieces in this tool kit. To name a few, this security set contains: Precision Head Screwdriver Security Fastener Tool,  n-usa-8 Security Screwdriver Fastener Tool,  #6, #8, #10 Tee-Cross, #4, #6, #8, #10 spanners (two-pronged head), 5/64", 3/32", 7/64", 1/8", 9/64", 5/32" security hex keys (Allen bits with a hole in the center), 1, 2, 3, 4 Tripley (appliances & bathroom fix-tures), #T8, #T10, #T20, #T27, #T30, #T35, #T40 security Tee-Star (torx with a hole in the center), and 1/4" socket adaptor.  It also comes with a 3 way solid magnetic screwdriver handle, steel shaft screwdriver extension with a magnetic tip for holding the hex shank bits, all in a plastic storage case (bit holder).

Digital recordings, especially High Definition (HD) recordings require extremely large hard drives in order to maintain an ample video library. It is said that upgraded hard drives allow you to watch more and delete less. Internal DVR hard drives upgrades are rumored at the time of this writing to go as large as 8,000 GB (8TB) for up to +8,000 hours of standard recording capacity. Increase the recording capacity of the existing DVR requires a special screwdriver and some unique tools found in this specialized screwdriver set.

 There are different DVR models use with different cable, satellite providers and used on several different broadcasting systems. More and more cable, IPTV, and satellite providers are using the DVR set-top boxes (STB) as a work-horse to supply their customers with HDTV:

To explore the option of upgrading the DVR hard drive memory capacity, the shortest rout to success would be using the special screwdrivers in this tool set. Truly the easiest way to not void warranty, damage the DVR, and add extra needed DVR hard drive space.
