VLC crash in win 7 x64 while watching IP TV

I use VLC to watch IP TV of my provider on the PC. Up until a while ago it worked very well. A few days ago VLC started crashing after a few minutes after starting the program. Sometimes it crashes after only a few seconds. This is what windows say about the crash:

I'm using ati 4870 and i haven't changed the drivers for a few months now, so it can't be a driver problem. I downloaded the newest version of VLC and am now using latest nightly version.
Any ideas what is the problem?

(gdb) backtrace
#0 0x65d4e51c in vlc_entry__1_1_0g () from C:\Program Files (x86)\VideoLAN\VLC\plugins\libavcodec_plugin.dll

Then it is prolly bug in libavcodec. Hopefully it will be fixed in next version.

Windows 7 x64.
In just the last day or two all vlc's from June or July crash immediately upon startup. Once I get back to my saved version (all 1.2) from January, it runs fine.
Tried to follow all the debugging information listed here but never got a well-behaved backtrace.
What I finally found is that I can actually get the latest 1.2 debug version to run successfully in gdb but only after continuing (gdb command = c) over several crashes. Weird - I'm not sure what to make of it.

I went to c:\users\ME\appdata\roaming and renamed the old vlc directory and now all the latest vlc's run just fine.
So it was something in the startup/config files.
