Re: [dvd::rip] Probably a transcode issue, but...

searching my notes I found this info: for ripping a well known blockbuster with
Leonardo DiCaprio and Kate Winslet I had to skip the first 275 frames. Your
mileage may vary.

Ahh, good call on the debug level, I've never used that one before.  When I 
execute this with a '-q 2', the end of the encoding gives me this:

So there does seem to be an issue with the audio track.  Just not sure how to 
read this or where to see around what frame it's having an issue.  So if anyone 
has any input, it would be gladly accepted.  :)

Full output from transcode is here, if you're interested:

I'm ripping all of my DVDs to .avi, and most have gone very well, thanks to DVD::Rip. I've had this particular a few times now, so I'd like to find out what's going on. The first pass seems to go fine, but the second pass finishes after a short period of time (10 minutes or so), and it produces an unplayable .avi file that is exactly 2056 bytes each time (with each dvd that experiences this problem). I executed the second pass manually, and I can't seem to find any issues, other than the lack of a file being produced, of course. Here is the output (I generally use ffmpeg, but this case shows testing with xvid4 as output, with the same issue)...

remove the first few frames, e.g. specify 25 as first parameter for the frame range.
Hmm, interesting tip. Can you explain why this should help? Probably it's worth an FAQ entry, but I like to have a bit more background knowledge ;)

I had this problem with less than 1% of all my DVDs. Entering the transcode
command in a command line including a certain debug level gave me sometimes
a message about CRC errors in ac3 frames. Skipping these frames worked for me.
I dont't really remember the exact number of frames, but it was always before
the movie started, so nothing was really lost. It's worth to try out different
number of frames. Maybe some kind of copy protection ?
