converting FLV to movie

[Bradamante]

hi,

I know there are many topics out there on how to convert movie files to .flv. This time it has to be the other way around.
I have 4 .flv videos, all from Google Video. I know want to include them in an offline presentation, that's why I tried converting them do divx/xvid/h264/mov.

two of the four videos worked fine, but the other two fail and mostly get this progress output:

Encoding started on Mon Oct 23 14:48:08 CEST 2006
FFmpeg version CVS, Copyright (c) 2000-2004 Fabrice Bellard
Mac OSX universal build for ffmpegX
libavutil version: 49.0.0
libavcodec version: 51.9.0
libavformat version: 50.4.0
Seems that stream 0 comes from film source: 1000.00 (1000/1) -> 29.97 (30000/1001)
Input #0, flv, from '/Users/bla/Desktop/bla.flv':
Duration: 02:43:03.9, bitrate: N/A
Stream #0.0, 29.97 fps(r): Video: flv, yuv420p, 320x218
Stream #0.1: Audio: mp3, 22050 Hz, mono
Number of stream maps must match number of output streams

the thing is, I got the same message for the second of my four movies too. If I remember correctly switching video codecs in the video tab helped, i.e. from MPEG4 [.AVI] (mencoder) -from the preset- to MPEG4 [.AVI] (mencoder). the conversion started and the result is fine in QuickTime and VLC.
now for my third and fourth movie the >PLING< comes shortly after starting conversion, while it doesn't matter what the target codec is, if .mov, mp4, h264, avi, divx, xvid ..

inverting the audio map does not help.
I noticed that my first two .flv files had a vertical resolution of 240 or 224, while the other two did not fit the 16x rule. however, I thought this issue counts only for the target resolution. but changing it from anything to 240 does not help.

ideas, anyone?
