no problem adding yet another overlay (which on is best?) I wondered

this purpose?
I use vobcopy to rip each title to a vob (instead of VTS_${TITLE}_$n)
then 2-pass ffmpeg the vob to transcode to mkv.
Makes batch transcoding rather fast and painless.

Thanks. Here's my progress so far using a Casablanca DVD as a test case.
Again, my goal by the middle of next month is to run videos on the
Kindle Fire. The spec sheets for the Fire says it's supports mp4. I
don't see any other obvious video formats.
1) I tried vobcopy. I got 6GB of files. I assumed ffmpeg was the next
step but didn't easily Google how to run it in this specific case so I
set it aside for the moment.
2) Tried dvd::rip because it was in portage. It got through the rip
portion of the job but then apparently couldn't find it's own files to
do the encoding. I tried joining the dvd:rip email list but I'm still
waiting for the moderator to accept me 3 days later so there's no
where appropriate for me to ask questions on using dvd::rip.
3) I tried handbrake which requires using an overlay.
3a) Tried the sabayon overlay but it wants to change too many files on
my system so I dropped that.
3b) Tried the multimedia overlay because it had the most up to date
version of handbrake. Unfortunately that didn't build
3c) Tried the init6 overlay with provided handbrake-0.9.5 which built
correctly and runs fine.
Handbrake goes directly from DVD to a reasonably sized (1.3GB) m4v
file. That file plays fine in xine and looks very good. Being that the
Kindle Fire only has about 6GB available for user content that gives
me 4 movies at a time which is fine for me but I suspect I can do
better.
My issue now (I think) is to learn to use ffmpeg to convert from m4v
to mp4. I'd like to see about reducing the file size a bit if
possible. At the same time the native resolution of the Fire is
1024x600 so I'm wondering about whether I can make the movies look
better by making the mp4 file somehow know about that size.
Anyway, I'v made reasonable progress for a few days of sporadic
effort. Hopefully I'll be able to make more by Nov. 15th.
Cheers,
Mark

The 300MB version was noticeably splotchy on backgrounds when displayed full screen on a 1920x1280 monitor, but not so much when sized to about the size of the Kindle Fire. - Mark

From the Handbrake manual: [quote] MP4 vs M4v They are the exact same file, the only difference is the extension. MP4 vs M4v. For MP4 files, HandBrake will automatically use the extension M4V when you pass-through audio (AC3), use SRT subtitles or have chapter markers enabled. You can simply change the file extension between .mp4 and .m4v as the file is exactly the same. There are no differences in the content or container itself. You can disable the option to automatically set this in HandBrakes preferences. [/quote]

Was your vobcopy line $vobcopy -i /path/to/mountpoint -n ${TITLE_NO}
-l -O ${MOVIE}_${TITLENO}.vob ?
My ffmpeg lines for dvd to mkv:
2.0 audio:
for a in 1 2; do schedtool -B -e nice ffmpeg -threads 4 -i $file.vob
-pass $a -vcodec libx264 -b 800k -deinterlace -acodec libfaac -ac 2
-ab 192k -y $file.mkv ;done
5.1:
for a in 1 2; do schedtool -B -e nice ffmpeg -threads 4 -i $1.vob
-pass $a -vcodec libx264 -x264opts preset=slower -b 800k -deinterlace
-acodec libfaac -ac 6 -ab 440k -y $1.mkv ;done
I use schedtool and nice to keep ffmpeg from hogging the cpu.

Downscale hd to 480p and de-interlace DVDs and other 480i content.
720x480 will look pretty good on a 1024x600 (WSVGA) screen.

You can use MP4box (media-video/gpac) to convert other container formats to MP4 if the audio and video are already in the proper format. For transcoding files, ffmpeg can probably do everything.
