It may be bad form to reply to such an old post, but I have the same 
tuner card, and this is my overall experience with MythTV and the HD-5500:

I installed Myth last January on an AMD64X2, and am still working on 
it.  EIT was not a high priority until now.  I am using gentoo 
media-tv/mythtv-0.20.2_p15634.

I found that about 1/3 of the channels had the "Use on air guide" flag 
set (maybe they are populated at random?), and naturally, they were the 
only ones that received EIT information.  After setting the flag on the 
rest, EIT is on every channel.

I found that when I used the channel manager to edit each channel to set 
the "Use on air guide" flag, the channel manager would usually crash 
with SIGSEGV, but at least the update took place. I had to restart 
myth-setup nearly each time I edited a channel.  To bad you can't 
globally update this stuff.

Mythtv is recording HDTV television just fine, and playback of 
recordings is fine.

Watching live TV is choppy, and mythfrontend usually eventually 
freezes.  I am not sure I care too much, since watching a recording is 
fine, even if the same program is currently in the process of being 
recorded.

There are anomalies in the mythbackend log.

I get bursts of about 40 of these for a minute (which was reported by
