I recently purchased a VisionTek TV Wonder HD 650 PCI. I installed the card in my new system, booted to Windows 7 and installed the ATI Catalyst software (drivers and ATI-MediaCenter). Using the ATI Media Center I then tried scanning for channels. The results was either no channels detected or static with no sound. I tried scanning with the cable connected to both the ATSC and NTSC connectors. I repeated this using Windows Media Center with the same results. I am running on a dual boot system (Windows Vista and Windows7). My h/w config: I7-920 CPU, X-58 mainboard, 3 GB RAM, Radeon HD 4850 video, TV Wonder HD 650.
I have an XP system (PIII 933 MHZ, 512 RAM, Radeon 7500, ATI TV Wonder analog tuner). I have the most basic cable offered though Comcast (called Basic 1? - limited to mostly broadcast channels). On my XP system I have been recording TV programs off and on since 2004. The TV wonder card on my XP system uses the WDM Capture driver for the Bt8xx chipsets and sees the cable channel fine in WinDVR. Why doesn't my new card on my new system find any channels when scanned? I saw in another thread that the Vista drivers don't work. The suggestion in that thread was to use the XP drivers. I am assuming this is a driver issue. I am using these media center programs to check the cable signal before trying out GB-PVR. Can anyone advise?
