An update on my finding.
I have download software like WinDVR, PowerVCR, BeyondTV to try on my USB TV Tuner. The result is either it loads the CPU or it does not recognise the USB tuner. Some of these softwares that claim to be less CPU intensive depends on hardware decoding of the TV Card. I also downloaded Dscaler but there are too many settings to set. I gave up.
Another software that I try is ChrisTV. This software operates at around 60% to 80% of the CPU. The only down factor is, it only works for Analog channel.
In conclusion, Digital TV thru external USB tuner is a no-no for G4. Digital channel or HD channel need the CPU to decode them in MPEG2 or MPEG4 (correct me if I am wrong). This will in turn load up the CPU. It does not matter if the TV tuner has hardware decoding or not, as long as it is USB, it will utilise the CPU to decode the images.
