I installed my old Hauppauge PVR-150 analog tv tuner in my new primary desktop that I built a couple of months ago and for some reason I was seeing laggy/frozen video that was extremely blocky and had green blocks throughout like the screenshot I took below.
After doing some digging I found out that the older Hauppauge PVR-150 does not work with computers with over 3Gb of ram due to the hardware address lines on the card. So I set out to find a way to get this to work on my new system without having to cripple the computer and remove 2Gb of ram.
After searching for a while it seems like the only options to get this to work with 4Gb or ram installed is to make only 3Gb of it usable. In order to do this, go to Start, run and type ‘msconfig’. There you will chose boot menu > advanced option and there you will see an option to change your memory. Change this to 3800. I originally thought this would solve my problem completely by sacrificing only a few Mb of ram, however once you reboot into Windows you will notice that the OS is only seeing the 3Gb.
I am unwilling to forgo the 1Gb of ram in order to get my old analog tuner up and running, so I will just leave everything as is for the time being.
