[dvd::rip] "create now" vobsub, leaves empty .sub file

[er0ck <erocks@xxxxxxxxx>]

Hi all, 
great program.  using it daily.  finally moved onto my anime dvds which need at least two language audio tracks (handles easily) and i want the original english subtitles in vobsub.  (ie, not text subs).

my problem is that
this:
mkdir -p /home/erict/dvdrip-data/ferris/avi/001 && cp /home/erict/dvdrip-data/ferris/tmp/ifo/vts_01_0.ifo /home/erict/dvdrip-data/ferris/avi/001/ferris-001-sid00.ifo && cd /home/erict/dvdrip-data/ferris/avi/001 && chmod 644 ferris-001-sid00.ifo && execflow cat /home/erict/dvdrip-data/ferris/tmp/ferris-001-sid00.ps1 | dvdrip-progress -m 1 -i 1 | subtitle2vobsub  -i ferris-001-sid00.ifo  -o ferris-001-sid00 &&sed 's/^id: /id: en/' < ferris-001-sid00.idx > vobsub13344.tmp && mv vobsub13344.tmp ferris-001-sid00.idx

of which the critical section is:
cat /home/erict/dvdrip-data/ferris/tmp/ferris-001-sid00.ps1 |
dvdrip-progress -m 1 -i 1 | subtitle2vobsub  -i ferris-001-sid00.ifo 
-o ferris-001-sid00

leaves me with an empty sub file.   yes, there are indeed subs in the vobsubs.

i can extract and create the vobsub by hand like this:

cat /home/erict/dvdrip-data/ferris/vob/001//* | tcextract -x ps1 -t vob -a 0x20 | subtitle2vobsub  -i ferris-001-sid00.ifo  -o ferris-001-sid00

and it works as expected.  it appears that the existing ps1 file doesn't have the subs in it??

also, when i try to use the 0 byte .sub file, mplayer sees the vobsub but its language is "enen"   i'm assuming from this:
sed 's/^id: /id: en/' < ferris-001-sid00.idx
?

i'm always using single rips (ie, not splitting the avi)
what am i doing wrong?  

thanks!
