VLC Player crashes when playing Youtube videos

Hi there,
recently, when using VLC Player 1.1.11 on my Windows XP SP2 machine, and playing a Youtube video, it crashes.
I simply paste the URL for the Youtube video (for instance
http://www.youtube.com/watch?v=8X_4O7ilniI ) in the
Open network stream... dialog box of VLC (which has been a feature for some time now IIRC), and next thing, VLC simply disappears. When I open up VLC again, it wants to send an error report.
- I've experienced similar crashes in the past when trying to play compact discs, but usually, after trying a few times, it would stop crashing. Not so with the Youtube videos, unfortunately.
- I just tried downgrading to 1.1.10, and it won't recognise the input's format. Could this be due to a change at YouTube's end?
- I haven't tried resetting my preferences, because I'm not sure how to back-up my current preferences. I would appreciate any suggestions.
Any thoughts on how to get VLC to play nice again? YouTube just isn't the same without VLC, at least to me.
Regards,
Lennart Goosens.

It is broken again since last night. Latest youtube.lua from git worked for 3 days. Seems they changed their site again
Might be that stupid new survey code.

It seems I'm too dumb to grasp lua pattern matching or i'm missing something else. Can't get it fully working....where is Pierre?

OK i got it working. Ugly hack I know. I never touched lua script before:

of course everyone is free to use my code as they please.

How do I update the Lua script in VLC on my Mac? With the script above?

As far as I know, you cannot update on Mac since VLC is all packed in a single DMG file (like most other MacOS applications).

Wrong
/Applications/VLC.app/Contents/MacOS/share/lua/playlist/ is the place to put the .lua

Sadly, this doesn't work for me
I get a tiny still picture for about half a second, before VLC Player exists.
What am I doing wrong? (edited to add, Am using VLC 1.1.11)
