contact trinitysoftwares.com ask for their video playstation software.
For the hardware i think any machine that is not manufactured 2 years back will do the job for you.
Personally i recomend P4 with HT (although i'm a AMD lover this time i recomend intel coz they said AMD have a heating effect although i didnt face any such problem)
256 DDR400 RAM and a SATA hard disk (the size depends on the numbers of songs you want to keep). If possible get 2 HDD , 1 for windows and 1 purely for the videos. you will also need a graphics card with video out pin. I am using Geforce 4.
Please ask again if you need anymore help
