I am using dvd::rip 0.98.2 with transcode 1.0.2 and have a problem on
many DVD's (well over half of the ones I've tried) when grabbing the
preview frame. In most cases the process stalls when the status bar
reads "Grab preview - title #1:" and I have to abort the process.
Sometimes it will start progressing and get to 99% and hang there. The
vob files play normally in media players, so the extraction to hard disk
was successful.
Below is the output of both the dvd::rip logging and the output when the
command is executed from a bash shell. My comments are contained within
angled brackets: <comment>. The output below is from an attempt where
the status bar get stuck at "Grab preview - title #1".
