Do you have the sound configured for your laptop? Could you please send
the vlc logging?

You could do the following:
1) Obeserve the bandwith e.g: with iptraf, because I suspect that either
the encoding is taking too long or the bandwidth occupation is to large
for your WLAN link.
2) Use another video codec, e.g: vcodec=huffyuv (CVS-only)

Well Gary there is no need to make the image larger, because the iPaq
cannot display it anyway. It got a screen size of 240x320.
