LOCK    - Everything's working...
SIGNAL  - Found something above the noise level
CARRIER - Found a DVB signal
VITERBI - FEC (forward error correction) is stable
SYNC    - Found sync bytes

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 NTSC_SYSTEM=1
• The device switching feature is still non-functional.
