Hello there,
 
Not sure if everything was setup properly or not. I tried to follow video tutorials and almost nothing was as I was expecting. I followed the following approach:
1. Installing the latest eclipse for RCP and RAP developers version 1.4.1.20110909-1818
2. Installing new software: XDE SDK Plugin 1.0.372
3. Trying to follow the second video tutorial: 
4. First of all, PAL package not found. Where is it, there is no PAL.xpa anywhere in eclipse folder and subfolders
5. To overcome the problem, I installed showInterfaces package from the repository
6. Followed the instructions and applied all instructions to showInterface package instead of pal package
7. I got ready for running the procedure, however I faced the following problem: there was no appropriate option for initiating procedure arguments; i.e there was no "XDE procedure" option in Run configuration section. There are only: XDE function tests, XDE procedure Test, XDE/PAL function
8. To override this problem, I tried to enter the arguments manually within the xde, setting constant values "default" for the device ID, and e.g. "fa 0/0" for the interface.
9. I defined connection settings within the inventory view to connect to my router. tested the connectivity with device console.
10. Running my first xde: I receive the exception saying: Perl executable not found at C:\perl\bin\perl.exe (probably cannot interact with "default" device)
 
A general comment over all, there is a gap between video 1 and video 2. Is there any continuity between the videos?
 
Many thanks in advance for your listening. Looking forward to hearing from you.
 
thanks,
Majid
