Although Audio/video cables have always been looked at as merely wires used to connect various media components, but in reality they play a vital role in the quality of the audio/video effects produced by the system. Quality cables are essential for quality sound and visual effects while poor quality cables are generally susceptible to noise and interference which harms the signals produced by the source unit. Also, low quality cables will deprive the consumers of the benefits of investing in a specific and expensive system of huge amount.

These cables are the medium to connect your equipments so that everything communicates with each other. Nowadays audio devices do not use analog signals to create sound, rather they use digital signals. The adoption of digital video sources and displays led to the development of digital video connection cables. Two popular options in digital video connections are HDMI cables and DVI cables. Although, HDMI cable does provide a way to carry digital audio signals, still it is widely used in conjunction with video, for example with high definition TVs and DVD players.

If you use audio/video cables of inferior quality, particularly during longer cable runs, the cable will lose information and the fine quality of signal will degrade. Despite the fact that high quality A/V cables can be pricier, if you bear in mind that all of the sound and video you hear and see get transmitted through these wires, it seems impractical not to invest some extra money to ensure that your wires are reliable and passing the best quality signal. Using superior quality cables might surprise you greatly with the quality offered else wise you won’t get the much desired results.

The WDTV eliminates the need to plug your computer in to the television. Prior to buying the convenient WDTV unit, I struggled with separate connections for audio and video, namely with s-video connections requiring an additional cable from my computer to the stereo. Well the WDTV eliminated the need for this.

The WDTV unit has two USB ports, rca video out and a HDMI out. Furthermore, it has an output for DTS. So very small in size, you can easily take it to a friends house to share videos and photos. Buy in conjunction with the portable Passport drive by Western Digital and you can take hundreds of gigabytes of media with you on the go. So small it can fit in a purse.

The unit comes with a small remote control. The interface is clean and to the point. You can easily browse between audio, video and photos. If your media has the accompanying data like title, artist or album you can easily sort and find the media you need. Furthermore, you can view folders either by the basic folder structure or you can set up playlists. The interface is very easy to use. During video play, there is a menu at the top you can access to turn on and off subtitles, zoom in or zoom out, or pause the movie. Furthermore, if you stop a video in the middle the WDTV player will ask if you want to start from the beginning, or continue from where you left off when you go to replay the video.
