You should defintaly rip via capture. Not only is the quality better, but depending on your hardware it may even be faster. In addition, most dvd players and vcrs support an copy protection scheme known as Macrovision. This is something done over the wire, and weather or not you hit this will depend on your hardware. If the hauppage cards support this (Anyone know for sure?), then your video will come out wavy with the colors all washed out and green. (Interesting article about this here http://septor.name/colby/bttv.html). Anyway, getting around this on a DVD is easy, just use ripping software!

The downside to this approach is that the media player in mythtv only supports certain video formats (Does not support AAC audio!). So injecting it into the mythrecordings may be troublesome (moreso than already is!). I just stick with mythvideo for just about everything (at least until Elisa gets farther along).

My friends! This is PLUG! Lets at least say "install handbrake in wine" until the linux handbrake is out. Alternatively, there are many many ways to rip a dvd in linux, and its gotten much easier. Check out:

yeah, you can:
use handbrake to rip the dvd on winXP on your laptop

or

just throw in knoppix and do a "knoppix toram" or "knoppix tohd=/dev/<foo>" so you can take the cd out after it loads and use one of the dvd rippers on knoppix.

just installing handbrake is a faster route though

You will need to use ivtvctl or v4l2ctl or whatever they are calling it
these days to setup the card with appropriate inputs, bitrates, etc.
Then check out myth.rebuilddata.base.pl
in /usr/share/doc/mythtv-backend/contrib. It will scan the recordings
directory, and prompt for all the info for any recording that doesn't
appear in the DB.

The other way to do it is set it up as a manual recording in myth. You
can hijack a channel from your existing set of inputs and edit the DB,
or use a different set of inputs (e.g. over the RCA red/white/yellow
composite connectors), and I believe you get the opportunity to fill in
the data.

XP can be better for ripping DVDs, as there are a few protection schemes
out there that don't seem to have work arounds yet. Or so I am told by
people I run into on the street ;)
