This doesn't apply to Robert's issue as it involves FireWire, not
Robert, I've been using Firewire with my MythTV set up for four years
now and other than (very) occasionally in the first year or so,
changes have always been rock-solid; certainly more reliable than the
IR blaster I used with my old TiVo.
(I doubt, by the way, that LiveTV changes are actually more reliable
than automated changes; you just haven't run into the issue when using
Live TV yet.)
If you were using an external channel-changing script that invoked
'6200ch' I'd tell you to look at that, as '6200ch' has an -s option
that may (or may not) make channel changing more (or less) reliable,
but given your mention of looking through the MythTV code I presume
you are not. So, do try using 6200ch with/without the -s flag and see
if it helps.
