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


 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.
