How can you program a sentry really big universal remote to your Direct TV HD receiver?

What I did to program. Hit "tv" and then hold down "code search" until it turns the light on. Then hit the on/off button until it turns off the tv......it took at least 20 times for me. Then hold down the "tv" button until it starts blinking. Then hit "ok". Mine then worked! *NOTE* Sometimes it takes more or less than 20 times. i hit mine about 35 before it finally turned my tv off, but in another room it only took about 13 tries. so don't get discouraged and keep trying!
