If that is the case, then that is a bug and you should report it to
linux-media with the specific failure cases. All of the ClearQAM
tuners that support QAM256 should be able to receive the same
frequency range. The ability to receive PSIP info though is
completely separate - if the tuner successfully gets a signal lock
then you should be able to receive any available PSIP info, and this
should not vary between tuners at all.
You need to identify whether your problem is really an issue with PSIP
info, or with achieving signal lock in general.

Yeah, the Teledongle is a board that doesn't fall into the above
category - it's *TOTALLY* unsupported - No LinuxTV developer is even
claiming that it should work. If you run Michael's development tree
(where he has specifically told people *not* to) and it sets your
house on fire, then it serves you right.
However, if you have a board that the LinuxTV project claims is
supported and it's not tuning correctly in certain cases, then feel
free to let us know.
