tovid not encoding whole video

[GoogleCodeExporter]

I have some video sourced from a PAL DVD and am trying to convert the video
to NTSC. I have frequently done this in the past by dvdbackup / dvdunauthor
/ select the .vob files to convert / tovid -in <vid> -ntsc -dvd -quality 8
-fit 8200 -noask -out <outstem> (sometimes specifying audiotrack if there
are more than 1 and I want a specific one). Usually this works fine.
However, sometimes I find video that not all of it converts. In these
cases, usually NEARLY all of it converts but the last minute or so is not
in the output video. Synch, sound, picture quality etc of what is there is
all fine, but it stops too early.
And I have one video, where the input is a mammoth 2-hour-20-minute 6GB
input .vob (taken off a dual layer DVD) which when converted as above
converts to 1 hour and 20 minutes and just stops in the middle. Again, what
is included is high-quality, sound is good, synch fine -- but it just stops
for no apparent reason before it's finished. The resulting MPG file was
about 3.8GB in size.
I thought tovid was supposed to split the output if it's too big for a
regular DVD? But then, I am not sure that is really what's happening here
because it didn't even get to the 4300MB limit. 

Tovid reported no errors while executing the conversion. I have 8GB RAM, an
Intel Core i7 920 processor and a little under 1TB of free disk space on
the drive being used for the conversion -- so it's nothing obvious like
that. It looked for all the world like a completely successful completed
conversion -- except that half the output is missing...

Specifying -discsize large enough to accommodate output solves the issue -- 
implying the split of files is 
not working properly. I think it is getting to the first split, then instead of 
starting a new file mpeg2enc is 
terminating, breaking the pipe and stopping the whole encoding process. Mplex 
then multiplexes the 
successfully ripped audio onto the incomplete video, producing output which is 
perfect as far as it goes 
but isn't the whole input.

Glad you found a workaround. The automatic splitting is something of a 
side-effect of
the (S)VCD support, and is probably not such an important thing to have with 
DVDs
(where you're more likely to want to -fit the video on a single disc). This 
feature
may be removed if/when (S)VCD support is removed, so hopefully won't be an 
issue then.
