I can confirm that I have exactly the same problem.

I am located in Melbourne, I can tune into all channels except SBS and 9 on both of my HVR-2200 (two cards in system).
I also have a DTV1000T in the same system, which can tune into SBS and 9 just fine.

The signal, snr, ber values coming out of the HVR-2200 driver seem very different to the DTV1000T i'm not sure if this has something to do with it, perhaps mythtv is misinterpreting it.

I have had this problem for over a year, ubuntu and mythtv updates over the year have had no affect on the problem.

The output of tzap scanning SBS ONE on the DTV1000T:

tuning to 536625000 Hz
video pid 0x00a1, audio pid 0x0051
status 01 | signal 0000 | snr 8000 | ber 00003fff | unc 00000000 |
status 1f | signal 2626 | snr ffff | ber 00000000 | unc 00000000 | FE_HAS_LOCK
status 1f | signal 2626 | snr ffff | ber 00000000 | unc 00000000 | FE_HAS_LOCK
status 1f | signal 2626 | snr ffff | ber 00000000 | unc 00000000 | FE_HAS_LOCK
status 1f | signal 2626 | snr ffff | ber 00000000 | unc 00000000 | FE_HAS_LOCK

The output of tzap scanning SBS ONE on HVR-2200:

tuning to 536625000 Hz
video pid 0x00a1, audio pid 0x0051
status 00 | signal 5454 | snr 0015 | ber 0000ffff | unc 00000000 |
status 1f | signal fefe | snr 00f6 | ber 00000017 | unc 00000048 | FE_HAS_LOCK
status 1f | signal fefe | snr 0000 | ber 00000011 | unc 00000048 | FE_HAS_LOCK
status 1f | signal fefe | snr 00f6 | ber 00000021 | unc 00000048 | FE_HAS_LOCK
status 1f | signal fefe | snr 00f6 | ber 0000001d | unc 00000048 | FE_HAS_LOCK

the HVR-2200 reports bit error rates whereas the DTV1000T does not, snr also seems quite low, perhaps the HVR-2200 has a different scale or meaning for these values.

If there are more test anyone can suggest to perform please let me know, I have been living without SBS and 9 for so long I have almost given up on my DVR! :(
