I also have an EC300 TV tuner which was supplied with my HP dv6519tx notebook.
In Australia it worked fine, but it does not here. I have downloaded and installed GB-PVR but could not get it to find any channels. I have since downloaded and installed DBViewer and it has found 28? channels (vision and audio) but I am not able to watch TV or get EPG to work.
I also understand that they require the use of PowerDVD (preferably version 8) and also the Monogram AAC decoder. I have PowerDVD 9 and have downloaded into c:\windows\system32\ the codec, but am unable to register it. I believe I have an NVidia 8300 GPU in my laptop (hardware acceleration unknown).
Can someone please help?
