I converted a DVD to .avi (specifically, xvid) using the excellent tutorial for Gordian Knot.

Using a card writer, I transferred the .avi file to an SD, put the SD in my Axim X50v, and tried to play it with TCPMP .71.

At first, rather than play the file, I got an error message telling me that the player did not support the ac-3 codec.

After much research, I realized that I needed to add the ac-3 codec for the .71 player, which I did.

Again, I got the error message. After turning my X50v off and on a few times, I finally got the .avi to play, but without sound. When I play other, non ac-3 .avi's I created (originally from DTivo), the sound is fine.

I can find precious little information about ac-3 and TCPMP, and am unable to get any further along in solving this problem without help.

Might anyone have ideas on what mistake I've made?

Thanks in advance!

Uninstall Tcpmp and all the codecs. Then install the newer version 0.72rc1 and the plugins for that version. It may just be that something didn't install correctly because ac-3 audio always has worked for me.

That did it. Thanks!
