[mythtv] Re:mythDVD module v0.0 released

[Michael Kedl]

I wanted to see what you think about my idea for an "updating status window."

I have an ugly script figure out the current frame, total frames, running time for 
the ripper and display this along with the % done, and guestimated time remaining.

I have 2 ways to display it currently: an old copy of mythdialog and Xdialog.
Both are simple standalone programs that have good points: small, no other interactions,
easy to use and test; and bad points: currently have to kill them and respawn every 5s
so there is a "blink".

The display appears a few seconds after you start a rip.  It is redisplayed every 5s
with a noticeable blink for now (I welcome ideas on what to use as a replacement display
program).  If you exit (press enter) the display it will not respawn.

I have modified the mythfrontend DVD menu slightly so that the rip is always in the 
background, and there are 2 new options to allow redisplaying the dialog if you
have turned it off to do other things.  The dialog should appear within a few seconds
after you turn it back on.

It is still pretty ugly for now but seems to work good for me.  I thought I would
see if you wanted to integrate it directly with your stuff.

I am attaching my files directly since there were only small changes in yours, but
I have added several.

mythdvdripfe = a new mythdvdrip frontend that simply dumps the output of mythdvdrip to
a logfile so I can figure out what frame we are at
mythdvdrip = small change to add the spawning of mythdvdripstat
mythdvdripstat = a program that figures out all the status info and displays it via
mythdialog or Xdialog
mythdvdripstop = a small program to kill the dang ripper off!
dvd_menu.xml = changes to allow restarting the status display; changed to XVID, stop option

Obviously a few of these things will go in the settings screen once it gets setup.

Oh, I had to switch the encoding to XVID because the Divx5 encoder simply crashes
when I run it.  Odd...

I haven't tried to get status of the VOB ripping yet.

I'm attaching mythdialog since it may be deprecated.

Cheers,
Mike
