I just installed the NeoTV SlingPlayer (NTV300SL). There is no onscreen remote on the TV screen. Picture and sound are fine. There is a function (accessed by Green Key or Menu button) on the NeoTV remote to change channels but it is very slow and only works for single digit stations or double digits of the same number, e.g., 22, 33, 44 etc. I can use the onscreen remote on my PC to change stations just fine. Any suggestions on how to fix this. Thanks.
