Screen capture? < Is this what you really want? I mean it sounds like you're interested in playing back your tournaments/games/sessions, so that you can watch/review/analyze, or perhaps have a friend or someone review them (or learn from them?).
For 'screen capture'... as in 'screenshot' I think by far the easiest method is to download free version 'ScreenHunter5.0 Free'. It is super easy to use (and this is coming from a guy who didn't know how to even turn on a computer a few yrs. ago). I keep an icon down in my 'taskbar', click it to open.. when it pops up you click on btn 'standby' (or 'capture now'), then you also have 3 choices,
[ ] rectangular area
[ ] Active window
[ ] Full Screen
(I always use 'rectangular area'.. position mouse cursor on corner of table/window click 'F6', then drag the mouse cursor to create your rectangle, let go of mouse btn & presto... there's your screenshot (I keep mine saved on desktop).
This might not be what you're looking for??
What I'm assuming you're after is something more like an auto-replayer. There's a freebie one called Popopop. With this auto-handreplayer you can drag & drop your HandHistory into it & have it play out the hand for you similiarly to as if you were watching the hand when it originally played out. You can also enter an entire tournament/session into the replayer & it will play it out in it's entirety (there's also a bunch of features/options with it, ie. playback speed, marked
hands you played (won/lost), etc. etc.).
This is a great tool & is commonly used by poker training sites & poker coaches (alot of the videos on poker training sites are using this tool for the videos).
For fun I just recently reviewed the very first tournament I ever played online (in '07), 'The Ferguson' in which I placed 2nd. I wanted to see how I played back then or should I say > how bad I played I played back then. I made some Hero calls & monster bluffs, lol 'ignorance was bliss', lol).
I've used this tool quite a bit & have found it to be really helpful (both for reviewing my own games & for reviewing HH's of some friends). There's something about watching a tourney (or session) play out 'after the fact' & objectively reviewing one's own play.
Just do a search for Popopop Universal Replayer.
