flagging is after

Not sure about glsync. See output at bottom.

[root at mythtv ~]# hdparm -tT /dev/hda1

/dev/hda1:
 Timing cached reads:   432 MB in  2.01 seconds = 215.44 MB/sec
 Timing buffered disk reads:  104 MB in  3.01 seconds =  34.54 MB/sec
[root at mythtv ~]# hdparm -tT /dev/hdb3

/dev/hdb3:
 Timing cached reads:   432 MB in  2.00 seconds = 215.68 MB/sec
 Timing buffered disk reads:   66 MB in  3.05 seconds =  21.65 MB/sec
[root at mythtv ~]# hdparm -tT /dev/hdc1

/dev/hdc1:
 Timing cached reads:   428 MB in  2.01 seconds = 212.57 MB/sec
 Timing buffered disk reads:   66 MB in  3.00 seconds =  22.00 MB/sec
[root at mythtv ~]# hdparm -tT /dev/hdd1

/dev/hdd1:
 Timing cached reads:   424 MB in  2.01 seconds = 211.07 MB/sec
 Timing buffered disk reads:   66 MB in  3.07 seconds =  21.52 MB/sec

No errors. Every so often I have seen a prebuffering pause, but they are
very rare. Rare as in I might see a couple in a day.

Wired, 10/100, on same switch. Performance on my comined FE/BE is about
the same, so no wire to traverse.

Nothing scary at all as far as I can tell. Nothing appears out of the
ordinary. 

LiveTV was set higher than 640x480. I've now set it to that in Recording
Profiles. I'm not doing any transcoding, so the files are all MPEG2.
What about bitrates and stuff? They are currently default. Should I
change any of that?

Also, all my changes so far have only been done in the setup in the
frontend, not in mythtv-setup. Do any changes need to be done there?
