[mythtv] DBOX2 LiveTV troubles (latest SVN)

[Tim]

You also might be interested in this change in dbox2recorder.cpp.

If there is a partial read of a TS packet the recorder spins hard using
much more CPU than it needs.

Here is a temporary fix, but I guess a poll would be better.

        // Check if enough data is available to process complete TS
packet.
        if ((stream->bufferIndex - readIndex - tsPos) < 188) {
-           //        VERBOSE(VB_IMPORTANT, QString("DBOX#%1: TS header
at %2 b
t packet not yet complete.").arg(m_cardid).arg(tsPos));
-         break;
-       }
+           //        VERBOSE(VB_IMPORTANT, QString("DBOX#%1: TS header
at %2 b
t packet not yet complete.").arg(m_cardid).arg(tsPos)); 
+                       // lets be nice to the cpu
+                       usleep(100);
+                       break;
+                       }

Once done the recorder uses about 1% of cpu on my system when recording
instead of 20-30%.

Oh and yes I have already found the startchannel problem but I thought
it was just my database was wrong, I had been hacking around with it for
a while.

There has to be a row in cardinput where cardinput.inputname ==
capturecard.defaultinput otherwise Myth is unable to find
cardinput.startchan.

If anyones interested i managed to fix this by changing
cardinput.inputname from MPEG2TS to DBOX2 for cardinputid='1'.

Dont know if this is a bug or anything but no amount of settings changes
in mythtv-setup changed this for me, and i had to do it by hand.

Will post more once i get channel change to cooperate.

Cheers,

John
