I got my Hauppauge HD PVR today, got it up and running and ready for F1, the file size is small enough and the reliability is good enough for me to record full length races, I am even considering doing a live stream of a whole race just for fun.
The manual from Steam (not found by me). Obviously the manual doesn't cover everything in the game, so need to wait and play it before too much judgement, but I predict it might be fun - much like some previous Codie games - if not terribly realistic.
