Pressing the "Advance" button on the TiVo remote once while watching a recorded event will put you to the end of the recording. Press it a 2nd time and you will be returned to the beginning of the show.
As to a "stop" button, I'm not sure what you mean by that, but if you are referring to an ability to stop watching a recorded event, go watch something else (live tv/another recorded event), then return to the program where you left off, you can accomplish that by either pressing the Live TV button, or the Left arrow button, which will stop the playback at that exact moment. You then have the ability to resume playing from that exact spot by going back to it. (You may already know all this, in which case I apologize for being so spectacularly obtuse. I personally have never had a DISH PVR, and if you had another function in mind, please let me know)
