i tried all the remotes and yes the ir is working. i even moved the sling box to another box thats differanent model and still not able to use the onscreen remote to change channel. i have looked all over to see if anybody had the same issue and don't see a fix on it. i have a mac pc and had my buddy bring his window laptop over to update the software. we had issue with it on his lap top and gave up. i been trying all kinds of remotes to work and nothing it working. can i get some help on this.
