In the UK the offsets (if present) are always +/- 167KHz. I haven't heard about offsets being used in other countries. > I'm asking because I would like to make the frequency for DVB-T channels > in VDR's channels.conf also be in MHz, and if that offset thing is in any > way standardized we could just add another DVB-T specific parameter to > cover the offset (like O0 = 0 kHz, O1 = +167 kHz, O2 = -167kHz). > > I wonder, though, why that offset is necessary, and whether the driver > shouldn't be able to tune to a channel at, say, 490 MHz - 167 kHz > automatically if it is given an inital frequency of 490 MHz.

No, trying to tune to a frequency of 488.833MHz by approximating to 489MHz doesn't work - I've just tried it. I think the "O" option would just make the channels.conf more confusing - it is much simpler just to keep the frequency the way it is, in KHz.
