Take a look here http://tw1965.myweb.hinet.net/Conexant.htm. I think the one you should try is x64 Driver 18.104.22.168.
I haven't tested this dirver. If you are willing to test it or contact the authors go ahead and post the results here.
Hi Everyone! Just to let everyone know that the conexant 64 bit drivers work for the TV@anywhere Master. Unfortunately the audio does not work, but the video works great. I use it as a survellience camera. Remember to use the PVR13 software located at MSI. Match the video driver with Conexant 2388x AVS Video Capture and the Audio to Conexant(unused device function).
What 64 bits programs exist to watch TV ?
I currently use DScaler, and it works pretty good, on watching, it sucks on recording. Does anyone knows a better program, preferably 64 bits (i don't have the system instaled yet) ?
