Is there a cord that can connect a tv with optical audio to a receiver that doesn't have optical audio?
Dish Network satellite receivers upgrade automatically, usually at night depending on your settings. You can encourage a software update by making sure the receiver is in "stand by" mode. If you have a Dish TV duo receiver, you must make sure both TV1 and TV2 are off. Wait a few minutes, if a software update is available you will see the message that your receiver is updating. If not, call Dish Network customer service.
