Video Codec

On my old win95 machine I had a ‘Pinnacle Systems’ PCTV card through which I recorded many video files from my camcorder. The software used a ‘Brooktree’ video codec to produce ‘.AVI’ files.
In order to play these files on WIN** machines, I put thecodec into the windows/system directory, and added the pointer to this file to the system.ini file.
ie; Put BTVVC32.drv into windows/system/
In system.ini [Drivers32] add
VIDC.BT20=BTVVC32.drv
VIDC.Y41P=BTVVC32.drv
VIDC.YVU9=BTVVC32.drvI now have a WindowsXP machine and cannot play these files. How can I get Windows XP to recognise this codec to play these .avi files.?
