Comment(by anonymous):
Just tried t5882_S2Api_4.diff on trunk (rev 19075).
At first i got the same modulation parameter error as mentioned above when
trying to tune to existing channels (DVB-S).
Then I thought I'd try to scan some S2 transponders before switching back
and ran mythtv-setup. It was able to lock and scan S2 transponders.
Having completed set-up the back-end was now able to get lock on some
channels (both S and S2) but got somehow confused about program IDs.
(2008-11-13 02:56:43.593 DTVSM(/dev/dvb/adapter1/frontend0) Error: Wrong
PMT; pmt->pn(1521) desired(1520))
It also failed to handle encryption, both for some (most?) previously
working S channels and all S2 channels which are supposed to be included
in my subscription. (2008-11-13 03:09:00.238 PID 0x2a2 status: Encrypted)
After switching back to the previous build all S channels worked as
before, decryption included. Whatever cleanup mythtv-setup did to
eliminate the modulation-parameter errors doesn't affect the un-patched
binaries.
----
Some more checks in the database reveal that the S2 scan hasn't got
mplexid right. I first configured the multiplexes (transports) manually,
then scanned them, Examining all channels on one particular mplexid (57),
I find that these instead should be pointing to mplexid 81 in
dtv_multiplex. The transponder in my database with mplexid 57 doesn't even
have valid parameters set which cause errors like this when tuning:

Your frequency setting (12128000) is out of range.
