Problems
- The plugin supports only those DVB cards with _one_ frontend (do any cards with multiple frontends even exist?), because I haven't yet figured howto do it without patching the VDR core.
- Disable the stream analyze to speed up heavy zapping sessions.
- The signal strength and signal-to-noise ratio values are comparable only between the same brand/model frontends. Due to the lack of proper frontend specifications those values cannot be calculated into any real units.
- If the OSD isn't visible, you've configured the OSD height too big or too small. Please, try to adjust the variable on the setup page before writing any bug reports.
- There's a shrinked default OSD height for NTSC users: make FEMON_NTSC=1
- The device switching feature is still non-functional.
