Hit the SELECT button to resume playback, not the PAUSE button.

Note that in the default mappings, P is not PLAY--it's PAUSE (which 
means "toggle pause").  If you really want, you can use Ctrl+P, which is 
PLAY, but then it will just play--not pause--so you'd still need the 
separate PAUSE button.

Jumps are in minutes (default of 10 min jumps for forward and back with 
DOWN and UP keys).  Skips are in seconds.  LEFT and RIGHT should do skip 
back/ahead by default, at 5s and 30s, respectively, but the amount can 
be changed in Playback Groups.  So, you should be looking at skips, not

Not a bug.  In MythTV, "this channel" refers to any channels with 
identical call signs.  If you want to treat 2 channels as different, 
assign them different call signs--that's exactly why call sign is an 
editable field in the mythtv-setup channel editor:  because it allows 
you to configure what "this channel" means.  You can do this for any 
channel.  The only requirement is that 2 channels should only be given 
the same call sign if they always show "substantially identical" content 
(meaning, IMHO, if they always have identical content).  However, any 
channels--even if they show identical content--may be given different 
call signs.

FWIW, the bug is the fact that MythTV records the same show when it airs 
at the same time on 2 channels with the same call sign (possibly with 
some video source tie in or something).  It's just not a bug that any 
one has cared enough about in the last 8 years to actually fix (and, 
yes, it's been around at least that long).
