+# CHANGE LOG:
+# 3/9/2009
+# Modded Bob's wonderful resumer script to work with the vdpau
+# options detector script someone anonymously posted to the wiki
+#
+#  http://www.knoppmythwiki.org/index.php?page=HardwareAcceleratedVideo
+#
+# You need to have both this and the vdpau-detector script in the same
+# dir for this to work properly.  Also, change your default mplayer
+# options in mythfrontend to read simply: # mplayer-resumer-vdpau.pl %s
+#
+# To tweak the shell commands for mplayer, edit the vdpau-detector script.
+# It has a small README inside it as comments
+# ENJOY!
+
+# 5/3/2006
+# Added last time started checking.
+# If this script is restarted within $tdiff (default 5 seconds)
+# then it will delete the file used to keep track of the videos
+# resume position.
+
+# PURPOSE:
+# --------------------------
+# This is a wrapper script to prove the concept of having MythTV
+# resume playback of previously-stopped video where you left off.
+# It's likely that a good solution will look different than this
+# initial code.
+
+# RATIONALE:
+# --------------------------
+# Watching 90% of a video and stopping causes you to return to the
+# beginning again the next time you watch it.  Remembering where
+# you were in the video and resuming at that position is a much nicer
+# behavior for the user.
+#
+# By default, mplayer spits out timecode information that tells you
+# where you are in the video, to the tenth of a second.  Mplayer also
+# supports a seek feature on the command-line.  We can make use of these
+# features to write an mplayer wrapper that will remember the last
+# position in a video file and resume to it on playback.
+
+# PARAMETERS:
+# --------------------------
+# see print_usage() below
+
+# FILES:
+# --------------------------
+# $infile, the video to play
+# $resumefile, the video's resume file (see get_resume_filename() below)
+
+# KNOWN ISSUES:
+# --------------------------
+# Mplayer misreports the timecodes on .nuv MPEG-2 files.  Currently, anything
+# captured via an HDTV tuner card and put into your /myth/video directory
+# will fail with this resumer.
+#
+# Current theories include the timecode having to do with the show's broadcast
+# time, recording time, or perhaps its upload time to the station that
+# broadcast it.
+
+# DESIGN LIMITATION:
+# -------------------------
+# If the video file to be played is on a read-only filesystem, or otherwise
+# lives in a location that cannot be written to, resume will fail.  This is
+# because the current implementation uses a file parallel to the video file
+# to store the timecode.
