Matrox's included DVD software was adequate. It functioned well and was easy to use. However, it failed to be as intuitive as alternatives such as PowerDVD. I suspect the primary difference is that PowerDVD allows for extensive control from simply right-clicking the screen, while Matrox's software requires the control interface to popup. Overall though, DVD performance and quality were both very good, with no frames noticeably being dropped. An important note is that Matrox specifies that at least a 400 MHz CPU is required for DVD playback.
Matrox's PC-VCR software was extremely impressive. The software enables you to control the TV-tuner by allowing control of station selection, video recording and screen captures. Additionally, the software supports Closed Captioning for those who use this feature. Playback quality was good, as is typical with most boards using a Philips TV tuner, as Matrox does.
