Video Evidence?

I've posted two videos on my YouTube channel. I hope the resolution is good enough that you'll be able to see what I see in the videos. You tell me, is this evidence of hacking or not? The videos show a view of certain log files on my Vista media center PC (all my main computing is performed on my Mac, which hopefully has still remained uncompromised). As I scrolled and clicked through the entries, I knew that something "just wasn't right". It seemed to show a lot of weird stuff going on, but I am not a techie, and have no way to tell whether there's any real evidence there. Check these videos out. I will upload a higher-def version of the complete 17 minute-long video on a free FTP server, TBD.

And finally, this is part two. Again, the quality sucks I realize.

Update [10/5/07]: It took some time since I am fairly new to video editing, but the first of two higher-def videos is posted online at a free hosting site called Files Upload. Direct link to part one: hacking_evidence_or_not_1.mov. Direct link to part two: hacking_evidence_or_not_2.mov.
