I'm a big time neophyte when it comes to this stuff, so please be gentle. I record some of my favorite HD sporting events from my DirecTV to my laptop to an external hard drive using a Hauppauge PVR. I recorded most in MPEG-2 TS format. I would like to edit them to remove commercials and be able to stream them through a Dune player. Basically, my question is . . . how in the world do I do that? I've done my research but, again, I don't understand much of these kinds of things. Is MPEG-2 TS an acceptable format or do I need to convert it to something else? I want to keep the nest quality possible, including what I believe has been recorded in 5.1. What programs (preferably free) should I use for conversion, editing, etc.? I have both PC and Mac, and intend to get a NAS for storage and streaming to my Dune. Any help, advice, or even references to good reading would be much appreciated. Thanks in advance.
