Hi there,
I use my AverTV to connect SVideo to my Foxtel box. I user the MCE blaster to cha nge channels on the STB. When I watch foxtel and change channels a couple of times the picture starts to stutter every 15 seconds or so. This is really annoying. If I turn the Tuner off/on it is ok until I change channels a couple more times. This doesn't happen on the Dvico.
Any ideas would be appreciated.
Cheers
Graeme
