Video transcoding stops randomly

[oliverlist]

Hi,
I encounter problems when trying to watch videos on my Sony Bravia KDL-32W5500. The videos are stored as mp4 (h.264) in avi containers on my local disk. The TV connects and starts playing the video, but stops randomly. I had that issue with several different videos; in fact there was no single one playing from start to end. I tried different configs:
exec: ffmpeg -i $infile -vcodec mpeg2video $outfile
exec: ffmpeg -i $infile -target dvd $outfile
all with the same results.
I always removed the partial cached mpg file before trying a new setting.

It seems as if ffmpeg simply stops transcoding the files, after a while the process ends. The problem is that it leaves me with an incomplete mpg file. The twonky process is not affected, it always stays alive when ffmpeg stops.

The strange thing is that if I run ffmpeg on the command line with the same settings, it converts the entire video without complaining. Unfortunately, I can't find any ffmpeg related output in the logs.
Any hints are highly appreciated.
Cheers, Oliver

My setup:
TwonkyMedia server 5.1.2 for Linux (x86) on a generic laptop, Intel T7200@2GHz, 2 GB RAM
Ubuntu 9.10, ffmpeg (unstripped version) installed from the repositories
TV is connected via ethernet cable, server is connected wireless

Hmm, no reply yet. I also posted this in the support forms, received a ticket and -- nothing. I bought the server a couple of weeks ago and wasn't able to watch a video yet, but that's what's the server is for, right? That's disappointing.
