Two questions about XMBC/XBian

[syco]

First, I thank you a lot for your help up to now. About that:

1. Alright, I will go and buy another cable to check it out. Btw, that graphic glitches do not happen to be there all the time. It seems to affect high-res videos only (Les Miserables was 1080). I will look out for further 1080 files to compare.

2. Okay, that did not work at all. I changed the sources.xml to get the security lock done and after that the Raspberry freezes, whenever I press on that directory to enter it (with my Yatse app on my handset). So, I deleted the security lock stuff from sources.xml and tried it over the GUI (XBMC settings). There I could do the same (set up a security code per context menu). Well, configuring worked easy, BUT when trying to enter again that directory, it just hangs (as before). That means, there is not coming up a menu/question to enter numeric code I specified earlier.

Does anyone know, why both ways lead to a freeze? I mean I can not do anything after trying to enter that directory. Btw, after a restart and removing the security lock, the directory can be opened/visited normally. For some unknown reason the security lock stuff kills my system. :-\
