Esteemed Zaurites,

Once again I appeal to your collective wisdom
to point out my stupidity. This is posted in the
software section but I'm not really sure how to
classify it.

The problem happens when trying to play the following
audio stream on an SL-C860 using mplayer (kino2


The audio is intermittent and one of the "percents"
on the mplayer status line is huge (believe it's
the audio codec cpu usage in percent). I'm fairly
confident that the stream is O.K..

For example, mplayer on my main linux box plays
this stream fine. And I even used mplayer's
"dumpstream" option on the zaurus and then played
that file on my main linux box. It worked again.
But playing this file on the zaurus behaves the same
as when playing it live.

To be fair, I tried another mplayer version on the
zaurus (mplayer-w100_1.0rc2.1-1_arm.ipk) and the
same thing occurs. So if anyone is inclined,
please try this stream and tell me what happens.

That and any comments would be appreciated. For
those who have made it this far, an mplayer log is
attached from playing "stream.dump" on the zaurus.
The "selected audio codec" part looks the same as
when playing the stream on the main linux box. And
note the several hundred % figure on the status
line near the end of the log. It's quite puzzling
at least to me.

Thanks for your attention.

With much thanks to ZUG resources, I've set up an ethernet over usb network between
zaurus (sl-c860) and linux laptop, with the latter using dialup-ppp for internet connection.

I plan to keep the laptop's dialup net connection for now but eventually would like to replace
the usb tether with wireless. So I hope to find out whether an 802.11b ad-hoc (peer to peer)
network would be one solution. Would such a wireless peer to peer network allow the zaurus
to access the internet using the laptop's dialup connection (as may be done using the
ethernet over usb)?

Any thoughts on this isuue would be appreciated. Thanks.

My simple network consists of the zaurus sl-c860 and a linux laptop, connected by ethernet over usb. The laptop is running RH8 (2.4.18) and is connected to the net by dialup-ppp.So far the network seems to be setup correctly.I can ping and ssh from the laptop to the zaurus and vice versa. I can even ping and ssh from the zaurus to the outside world.

The problem is when I fire up the zaurus netfront browser, it doesn't connect to the net. There's a connection prompt (No connection to the network. Connect now?) to which I reply "yes". Then a connection setup error dialog appears (Cannot found the device card for communication).

So it's as if the browser isn't aware of the ethernet over usb. I've gotten this far by rummaging through the various user groups. Any recommendations would be appreciated.
