Depends whether you consider your time cheap.  Cheapest in terms of 
dollars is probably http://lirc.org/receivers.html .  Cheapest in terms 
of time would be a solution like a) a wireless keyboard, b) a USB remote 
(possibly RF, like the ATI Remote Wonder or X10 Lola) using either 
kernel "keyboard" drivers or LIRC, c) a commercial receiver like IRTrans 
( http://www.irtrans.de/ ) or d) a ready-made LIRC homebrew receiver (

It's more likely the quality of the capture card (since you're getting a 
good picture on the PVR-x50).  Replacing the BTTV card with a PVR-x50 
would probably give you good results.  If you really want to spend time 
on the frame grabber, check out 
http://www.gossamer-threads.com/lists/ivtv/devel/17953#17953 for some 
approaches to consider for cleaning up your signal (although I wrote it 
about a system using PVR-250's, the same info applies to other cards).

And here I see this as a benefit of Myth over the TiVo...  (Why would I 
want to waste power/cycles/whatever recording the channel my tuner 
happens to be on when my MythTV records every TV show I might possibly 
want to watch, so I have enough recorded programs that I *never* watch 
LiveTV?)  Chances are, once you get your recording rules set up 
properly, you won't miss this feature.

You can use the EXEC action to execute an external command.  Therefore, 
if you set up a script to put your system in the mode you desire (i.e. 
with xset, hdparm, etc.), you simply add a button to the menu to call 
the script.

Set the recording group on the recording rule.  If you have recordings 
you would like to move into a group, press "Info", select "Recording 
Options", then "Change Recording Group".  To sort by group, press 
"Menu", and select either "Change Group Filter" or "Change Group View" 
as desired.

The default key mappings use "P" for the Play/Pause toggle (i.e. one key 
for one action), and mark position is "Select" (either "Enter" or 
"Space"--assuming you've chosen "Alternate Clear Saved Position" in TV 

Therefore, it sounds like your remote configuration maps the play button 
to "Select"--which causes the selected video to play in the PlaybackBox 
but not when playing a video.  Usually this is done for remotes that 
don't have buttons to waste (i.e. mapping both the play and pause 
buttons to the letter "P").  So, either change your remote configuration 
(and lose a button since two will send the same command) or learn to use 
the remote the way you have it mapped.

Sounds like you've done some homework.  :)
