My Xbian stopped buffering by itslef !. How it was possible ?
I just moved it to another house. But all config and server leave the same.
In both houses the same NAT and DHCP. Mhmhm....
Now i feel scary to configure screen calibration - because Xbian buffering
may return Smile

...
I need to say that XBIAN vs other distribs running faster and without
unexplayn retention. I have try most popular distribs and Xbian
realy work correctly and fast. Xbian motivating me to continue make
my home project on Raspberry. Only buffer my future question Smile

Thank You

That could be due to:
- Wireless signal strength
- Wireless signal speed

Oh no... After screen calibration it happens again. Then I restored original
guisettings.xml and buffering disappears. Now I comparing these two files
and cannot find any differences exept:

when buffering:
<resolutions>
<resolution>
<description>1920x1080 @ 60.00 - Full Screen</description>
...

when no buffering:
<resolutions />

I have no WiFI...

The video playback should run on 24hz, not on 60hz.

depend on Video out settings Wink

not all have 24 support so it may run on any frequency 50/60Hz too.
I reading more people reporting this kind of behaviour after XBMC update to 12.1, not just us, same for OpenELEC and Raspbmc.
So it would be somewhere inside of XBMC, I would say

No matter 24 or 60 - buffering anyway

btw, why do you need screen calibration ?
So many eople get confused and always trying to solve simple thing the hardest way. Not saying is your case, but can you tell how you are connected to the TV, what connection, what is the TV (model) you have?
As I never needed to calibrate the screen, and I use XBMC for more than 7 years, I've installed the XBMC for many people on many different setups, and honestly, never needed to calibrate it.
There is an simple thing what most of the people overlook always, and that is the overscan setting in TV. 99% of TV's has this option.
And also 99% of TV's has the aspect ratio for all inputs on TV pre-set to Auto, where this cause the trouble to picture reproducing from external sources.
So my recommendation, not just for you but for all is to start from there and not to go and calibrate the screen in XBMC settings. This option should be as the last to do.

So
-check the aspect ratio on the TV for RPi input (make sure you have no Auto mode but forced 16:9)
-check the 16:9 overscan (make sure is OFF for RPi input in your TV settings)

Rikardo.. Thank You.. I realy found option in my TV and now I don't need a calibration.
I restored all my xml file in userdata dir to defaults.. But damn - now buffering... Hrrrrrrrrrrrrrrrrrrrrrrrrrrrr
I can't identify - What causes buffering ?!?

**rikardo1979** · 30th Mar, 2013, 04:15 AM

nice one

so any chance you start from fresh XBian flash on SD card ? you know, just to save some time to fix something if no need Wink

Avriukas2 · 30th Mar, 2013, 05:23 AM

After fresh install - Buferring again.. Smile

in XBMC forum tells that HeadEnd is broken..
may it's a reason of all my problems... Smile

look at the codec debug info ('O' on keyboard). You can analyze, what is the stream, audio, video, cpu load, network speed. then you can think what is the problem.
