conversion dv to DVD doesn't work

[ulla]

I have a 23GB-dv-folder of citizen kane (imported with a/d converter) on an external hard drive (60GB). Now, if I open it in ffmpegX, set conversion to DVD with either DVDffmpeg or DVDmpeg2enc (to the external drive, again), what I find after the conversion is an .mpv file without sound.
Only days ago I did the same conversion with "twin peaks-fire walk with me", and it worked great (the only difference was another external drive, that I had the .dv file on (Lacie drive with 160GB). Then I had the necessary AUDIO_TS and VIDEO_TS folders created, and the DVD works fine now.
Since I have no idea, what the reason for this strange behaviour could be, please help (I tried about 6 times with different encoding settings, no luck yet).
what could be going on here?

Is it a MOV containing DV or DV? You could also post the process output for inspection.

[ulla]

thanks for your response,
it's not a mov, but a dv-folder, with quicktime-thumbnail.
it was created with formacs studio tvr, which, as the manual says, creates dv-format.
what exactly do you mean by "process output"? the output mpv-file is erased. Should I try again to be able to post a picture?

The process output is what appears when you click the blue "i" icon in the Progress window.

Now here's the process output:

Try to enable the option "Decode with Quicktime in the Options tab to see if it helps.

[ulla]

Thanks again, it worked this time ("encoded with Quicktime").
funny, though, it ended up in three files:
...dv.ff.mpg
...dv.ff.ac3 and
...dv.ff.DVD, containing the necessary folders (AUDIO_TS, VIDEO_TS)

-is that the way it's meant to come out?? (sorry if I sound stupid, I'm still new to ffmpeg)
