Hello forum,
I have used the dreambox since a few hours now, and I see firefox using 80 to 90 CPU time. As there is no network activity, I suspect the "newsticker" to cause this phenomena. If I'm correct, does anyone have a hint how to get rid of this newsticker? I use Helenit final on a Dreambox 500+.

Put this in Firefox and you'll see all your cpu power consumed by this nonsense:

Firefox under Linux btw ;-)

That's right. I use Firefox under Linux too, and Firefox 2 caused a big cpu load. Firefox 3 handled it better.
You can temporary disable it in the webif menu itself. Somewhere right in the screen there's a menu to disable the newsticker (don't know the name as I don't have a dreambox here right now)

ok, thnx, under "about pli" there is a drop down with "News ticker". And indeed, this toggles it on and off.

I just did, and CPU usage is 0-1% (Firefox 2.0.0.14 on Windows XP). I can't detect any abnormal behaviour here...Put this in Firefox and you'll see all your cpu power consumed by this nonsense:

Restarting FF makes it come back again. I'll try to add it to the blacklist of my squidGuard. Or is there a way to disable it in the shell of the box?

You might have an other problem.
FF is notorious with regards to memory consumption, the longer you run, the more memory consumed, the slower it gets, and the more CPU it uses. This is especially noticeable when using Javascript (with the ticker does). In that case a restart of FF solves the problem (for a while). FF3 seems a lot better in that respect.

There's no way to disable it permanently. But I think it's even a bug in the Linux Firefox 2 version (Firefox 3 handles it better, Windows doesn't have to seem this problem)

I know. But that is not the problem. As soon as you load the ticker, it starts consuming CPU power. As soon as you stop the ticker, CPU consumption drops to normal proportions.
But there's someting else, maybe more severe: when choosing another (radio) station, the browser is getting the EPG a few times per second:

The fast screen refreshes while in radio mode is a known problem (since many images). In TV mode this problem doesn't exist. We couldn't find the bug, though.

It stops when you click on the "Radio" button (left pane). When you select another radio station from the list it starts again. It was apparantly made for showing the AGC/SNR/BER in the toolbar.
Maybe this helps? Unfortunately I'm not a programmer so I won't be able to help.
Addition:
when clicking the "Radio" button on the left, the refresh time increases from a few times per second to something like once per 10 seconds.

For the rest the box works perfectly well. I only had to use the old stable version Helenite Final because the 4-way antenna switch did not work well with the latest Iolite 2008 Edition. And last but not least, the webif does work properly under Opera-9.50 (Linux). Which of the two causes this problem, I have no idea...
Btw: putting the ticker URL to the blacklist of the proxy "resolves" the ticker problem for me at the moment

The webif reloads continuously when some pids are unknown. Since radio services don't have a vpid, it keeps on reloading.
data:
var vlcparms = "http://192.168.64.109:31339/0,0105,ffffffff,151b";
zap.js:
function vlcStart()
{
if (parent.data.vlcparms)
{
if (parent.data.vlcparms.indexOf("ffffffff") == -1)
{
...
}
else
{
parent.data.location.reload();
...
}
}
...
}
