SichboPVR v3.0 can't include its own codecs for legal reasons. Luckily most decoders are already present on the majority of modern Windows 7 or 10 PCs, so a lot of the time video works fine right off the bat. If SichboPVR displays an error when trying to view a channel, you need to jump through a few hoops.
The quickest catch-all fix is to:
For video types it is recommended to stick with the default DXVA2 one if yours is currently working fine, and if under the F1 Key > Video it says that the mpeg2 and h264 types are being accelerated. The recommended DXVA2 decoder uses your display driver's built-in decoder, which means it should be using near zero CPU and saving a lot of electricity in the process.
If there are no errors but you have no sound and the app is using 'Microsoft DTV-DVD Audio Decoder' for its AC3 or AAC audio decoders, try switching them to LAV Filters instead.
If you're using LAV Filters and still get an error check that your LAV Audio Configuration app (from your Windows Start menu) has the AAC, AC3, EAC3 and MP2 options ticked under its Formats tab. Similarly for video, ensure your LAV Video Configuration app has the MPEG2, H.264 and H.265 options ticked under its Formats tab.
