[FFmpeg-user] How to make AVI files from LG RH7500 recording which will play on it?

hi list members,

I have subscribed to this list because I have spent the last few days desperately trying to convert a VOB file (made by my harddisk/DVD recorder (LG RH7500 ) into an AVI, which can also be played by the same harddisk/DVD recorder (LG RH7500).

So I just want to make AVI files from my own recordings. Afraid this device is quite choosy with AVI files.
However it does seem to play most of the AVI's I find on the internet, but I have BIG trouble making one myself which will play on the LG RH7500.

I did succeed to make AVI test files with ffmpeg which play fine on my other DVD player (Provision), but I would still like the files to be compatible with the recorder aswell, before I start converting en masse.

But back to the LG RH7500 recorder: with ffmpeg I succeeded in making a test file of 5 minutes playing time. At first I thought I'd done it. But after a few secs it just quits playing and I get returned into the file menu.

I would be very gratefull if some expert could provide a clue, or even better a command line I could try for ffmpeg (Windows build).


All info concerning AVI files from the LG RH7500 recorder manual as follows:
