I thought that the reason for scanned frequencies not matching "real" frequencies, was due to the differences in cards and equipment. A slight variation in components will lead to a slight variation in the settings required to achieve an "actual" frequency. So although the card *thinks* it's tuned to x.73 it's actually tuned to x.5.
There is no 100% accuracy in these (cheap) technical tuner chips.
AFAIK the allowed range in the De-Modulator of a tuner is 5MHz.
So it will tune to the advertised frequency and will find a lock within that range - if signal quality is sufficient - as a positive lock.
In my case above, the offset reported is only 0.25MHz...so technically well within range.
However, computers are "idots" when comparing numbers for being equal
