I know this thread is a bit old, but still seems valid to contribute.

What underwear do you like to wear- in what order, if more than one? (1- Fav 5- Last Option)
1. boxer briefs
2. boxer
3. commando
4. briefs

Why is number one, or what you primarily wear, number 1 or your primary choice?
Decent support while still allowing some movement and breathing room, but doesn't bunch up usually.

What names of underwear do you wear? i.e. 2(x)ist, CK, Chereskin
(I would love to see the different brands, from around the world)
Mostly Hanes but I have a couple fancier CK ones.  Don't need or care for anything particularly fancy.

Where do you get your underwear?
Online? (What Sites?- remember do not use WWW or HTTP://)
Only one time, place called international jock.

Store(s)? (Which ones / Why?)
Target, Walmart, K-Mart, etc.

What is your Favorite Color of the underwear you wear?
Blue, black.  Sedate red, blue or green plaid/tartan/stripe/etc patterns aren't too bad.

Hey.  New to this site, but not really new to torrents, or gay porn.  Don't have much to contribute other than bandwidth and maybe some discussion as I don't really collect rare porn… or buy new porn.

If you want to take a bit of time and effort, ffmpeg can do what you want.  It can reasonably clip a video with no need to transcode, but you need to do a bit of legwork, like making sure you only start on a keyframe, and of course, using a command line, and learning ffmpeg's options.
