Plextor ConvertX PX-M402U - Page 1

Plextor is the leading manufacturer of DVD/CD Recorders. However, in an attempt to provide more complete solutions covering from DVD creation to DVD recording, Plextor has introduced the ConvertX series for real time video encoding. Their latest product in this series is the PX-M402U.

The PX-M402U follows on the footsteps of the M401U, but has real-time, hardware based MPEG-4 encoding, along with real-time Dolby Digital audio encoding. This external device is also suitable for laptop users, making encoding as easy as possible. It can capture DVD quality video from multiple sources, such as TVs, VCRs or camcorders.

- Features

The device uses the Hi-Speed USB2.0 interface, making it compatible with all computers running Microsoft Windows XP. Of course, it can be connected to a slower USB1.1 port, but this is not recommended, since the transfer rate on such ports will not allow for real time video encoding. On the other hand, USB2.0 connectivity allows high bitrate video capture using MPEG-2 compression, maximizing data throughput to the host computer.

Most available encoders will encode audio in normal stereo or wide stereo 2-channel format. Dolby Digital is a key feature of the M402U. It converts the audio input to Dobly Digital channels, muxing them with the produced video stream. However, this is not hardware based real time encoding, but instead, the software handles the audio signals in such a way that produces Dolby Digital audio.

The PX-M402U is the first capture device to be officially DivX certified. Rockgroupplc laptops & desktops driver download for windows 10 windows 7. This is a very interesting feature, since users can benefit from this popular format for sharing videos easily over the internet.

Users can select from a wide range of available video formats that the device will use to convert video. MPEG stands for Moving Pictures Experts Group. MPEG-1 is used for VideoCD creation and was the first format introduced by the group. The MPEG-2 format is used for DVD creation and offers advanced video encoding producing better quality. MPEG-4 is the latest format created by the group, providing high compression levels, making video sharing popular. The DivX codec is the most popular MPEG-4 based codec, created by DivX Networks.

The DivX codec has several coding profiles to ensure compatibility with most stand-alone DivX players. For example, the 'DivX Home Theater' profile can be used to encode files that are meant to be played in stand-alone DivX players. On the other hand, the 'DivX Portable' profile is used for creating video streams compatible with all portable devices, like palmtops. The following table is provided by Plextor, showing different recording formats.

- Retail Package

The retail package includes the PX-M402U, audio and video cables, s-video cable, USB2.0 certified cable, power cable with AC adapter and scart adapter. The audio and video cables provided are not high quality cables, but standard low quality cables, 1 meter long. These cables may produce extra noise in the video files created by the device, but this is something that only advanced users should consider. Most end users will not have any problems with the provided cables.

The device comes with 2 years On-Site Collect&Return Warranty for all EU countries, Norway and Switzerland. For the U.S.A., the device is covered by a 1 year warranty.

The User's Manual in 4 language and a quick installation guide in 16 languages are also included. An additional applications CD is provided by Plextor with Intervideo WinDVD creator 2.0 and WinDVD player 4.0, along with the device drivers. You can read comments on this software by Intervideo in the following pages.

Video and audio connections are located on the front panel of the converter. The above picture shows a simple description of every connector shown. The device has two operation leds. The power led lights blue when the device is connected to a computer and is powered on. The recording led lights red when the device is converting/recording video and audio from any external source.

On the rear panel, we can see the power connector and the USB connector. You might notice that there is no control panel available. The device's control is handled through the bundled software included in the package.

- Installation

Video converter installation was never as easy as it was with the PX-M402U. The only thing you have to do is insert the disc provided by Plextor containing the device drivers and you are ready to go.

The following screen was shown, which helped us install the device drivers without the need to use Window's device manager. The whole procedure was like installing any ordinary software package.

Remember not to connect the device before installing the device drivers. The software checks to see if the device is connected and it warns you of every error found.

When the installation is complete, you can connect the device and it will be recognized automatically by the operating system. All you have to do from this point on is connect the appropriate cables and you are ready to go.

- Testing software/procedure

It should be noted that throughout this review, and especially on zoomed images, by clicking on images, a full sized high resolution picture will be shown for comparison reasons. In general, we were interested in capturing still images, moving pictures and test screens. These test screens are used mostly to investigate the clarity of the external converter. Of course, we used not only light images and scenes, but also darker ones. In any case, the created image files/snapshots are compared with the images included in the 'Plasma TV Demo DVD' provided by Pioneer, without any kind of conversion or compression.

Semtech sx9500 driver. We tested the device on several computers, to ensure that the minimum requirments are correct. The device produced audio/video synchronization problems with CPUs lower than 800MHz. We also tested the device with several Pentium IV systems, but the results were the same, regardless of CPU speed. We decided to use the recommended configuration that Plextor suggested, i.e a Pentium IV at 1.6GHz.

In order to perform our tests we used:
