**ERROR: [???] Unable to read from C:\Documents and Settings\...\Desktop\Encoded_audio_1.mp2.

There is an encoded audio mp2 file, but it's empty ("0 bytes")
The audio on the original is PCM.

dvd2svcd rarely lets me down. This is one I don't want to give up on. I've converted the audio with Goldwav and vdub, but get the same results.

Any ideas?
THANKS
