Just for the record dd_rhelp completed in around 8 hours. The
resulting iso was corrupted, that said mythvideo would at least start
the main feature, but the video was corrupted and it hung.

I did download ddrescue as Michael and while it took 4 hours it did
copy the DVD, perhaps I'm being picky but I would have expected it to
take a lot less time than that. I could watch al the content in less
time. Perhaps using wine and windows tool I could do it but that is
not what I'm after.

Anyway, thanks to all for suggestions. If the time really annoys me
then perhaps I might look at the windows/wine tools in an attempt to
find out why they are faster and see if we can't get a fully open
source friendly version. For now ddrescue looks like my best bet.

Martin
