I didn't think Roddy came off poorly in the video. He's clearly super talented, just wasn't the best for the job.
Well, to each their own. I definitely came away from the video thinking "holy shit, Derek totally bungled that audition", and I assume I am not the only one who had that impression. And that alone should give Roddy cause for concern.

I'm sure DT wouldn't have asked Derek to audition if they didn't think he's got proven record. Frank must have plenty of contacts to do background check for this kind of stuff and, I'm sure Derek's ability is not the reason he didn't get the job.
And, he's got great personality and very easy to get along with, so, on a personal level there shouldn't be any clashes either.
But I think the reason Derek didn't get the job is difference in the "musical chemistry" and his attitude about not expecting any changes in his life if he were to given the drummer's stool in DT.
Rumborak, I agree with you that after seeing part II, I also thought Derek has no chance. I noticed him admitting plainly that he didn't really prepare thoroughly to be able to play the songs(something along the line) and it might have contributed to his playing during the audition. Also, I noticed that after the audition, the band's reaction was a little less enthusiastic compared to MM and MM's.
