I recently installed MediaPortal (184.108.40.206, Windows 7, Terratec Cinergy S2 HD PCI) and noticed two problems:
- A channel scan did not recognize any channels (unlike TerraTec Home Cinema)
- After importing a channel file and trying to preview a channel raised the error message “Preview failed: UnableToStartGraph”
The scanning problem was fixed by opening the TV Server Configuration, navigating to TV Servers, (computer name), (card), selecting the DvbS card type, “Edit”, and selecting DVBS as preferred network provider (it had been set to Generic before).
This allowed me to scan channels using DiSEqC = None.
The preview problem was fixed by selecting CyberLink decoders under Codecs and Renderer where available, and selecting Enhanced Video Renderer (EVR) in the Video Renderer tab.
