 I profiled mythtv today and found a bottle neck in the DVB event parsing.

 Without the patch dvb_decode_text() takes about 93% of
 SIParser::!ParseTable. The patch drops this to 4%.

 I'm not sure if the caching in a static patch is acceptable (in particular
 if it's threadsafe). But it is working fine for me.
