Post subject:  Certain DVB-S Channels failing on R5.5

Recently my provider started moving channels arround in preperation of rolling out HD and since then some of my channels have stopped working.
At first I thought it was just that I couldnt get my multiplexes right, but more and more of my channels stopped working.
The out of desperation I install the latest MythBuntu 8.04.1 restored my channels and dtv_multiplex and suddenly all the broken channels started working. I have 2 other friends with a similar setup (not hardware) who are experiencing the same problem with R5.5, the one friend says he can record the broken channels and then view it, but not view it live.

I have tried going through the changes booked into mythtv-0.21-fixes but there are just to many, MythBuntu is on 0.21.0+fixes18207.

I have gone through the backend/frontend logs, but nothing looks wrong except I get this on the broken channels sometimes get this:
2008-08-31 10:48:44.512 DTVSM(3) Error: Wrong PMT; pmt->pn(3144) desired(591)
2008-08-31 10:48:44.515 DTVSM(3) Error: Wrong PMT; pmt->pn(590) desired(591)
2008-08-31 10:48:44.516 DTVSM(3) Error: Wrong PMT; pmt->pn(3173) desired(591)

However if I do a dvbscan I can see the relevant channel on 591

Or I get this:

2008-08-31 11:11:20.401 DVBRec(68:3): Saw PAT but did not write to disk yet
2008-08-31 11:11:20.452 DVBRec(68:3): Saw PMT but did not write to disk yet

After a while I will get an error stating that there was a problem with the stream and I once I OK I get back to the main screen.

Any help would be appreceated, also is there an easy way of getting an updated version of mythtv, or do I have to recompile by hand ?
