i put dvr/remote problem because i don't know if it's the remote or the dvr that's the root of the problem. my setup: i have an hr24-200 and an hr24-500. a couple weeks ago, the hr24-500 started giving me trouble. the problem is it's not responding properly when using the remote. sometimes i have to press the remote 2 or 3 times for it to respond. also, when i'm scrolling through the guide and hit the scroll down(or up) button, it will respond as if i hit it twice. it's really driving me crazy. i've changed the batteries in the remote as well as doing a red button reboot (couple times)....didn't help. is there anything else i can do before calling customer service?
