Just got the Kworld UB435-Q USB ATSC Only tuner stick. I am running windows xp pro SP3 and mediaportal. I installed the drivers for the stick and device manager shows it working properly. I can watch TV with the included junk software, although it is very choppy another issue for another day. However, mediaportal shows that no capture cards or tuners are available. I have uninstalled and reinstalled numrous times. Does anyone know how get the USB tuner to be recognied by mediaportal? I have read different reports that if they do not work in XP MCE then they won't be recognized in MP either. Is there a work around for this?
