OK, after watching many awesome videos I decided to bookmark your site, Pro.
What I do wonder, though, is how do you get trailers in their original resolution, aspect ratio and frame rate? I never thought the "Samba de Amigo" trailers ran at 60 FPS.
I seek out press kits, promo DVDs, game demos, store display videos, stuff like that. I collect promo media, sometimes spending $$$, effectively making my site a museum. If I can't get a particular article, I'll request a rip/copy of the article's contents. The Samba trailers are 60fps because the videos from Sega's press site happen to be 720p/60fps. The Zelda 2005 trailer was DV NTSC-interlaced, so I spent a night to manually clean it up. Source quality varies. Soon I'll have captures of the N64 VHS promo tapes, and the TGS 2002 Resident Evil 4 Progenitor trailer (recent $130 eBay purchase).
In nearly all cases I end up cropping and resizing footage to fit my formatting specs. I want them to make sense to our eyes, make sense to display monitors, not waste space with black borders, and accurately represent the source within reasonable bandwidth tradeoffs.
