I just had an HR20-700 replaced with an HR21-100 (hoped to get an HR24 but did not). It is networked via whole home DVR and it is connected to the internet (VOD works). Whenenver I try to use the TV apps I have to push the right arrow button several times for the banner to come up. When it does and I open the App store and select any app it freezes up and I have to select "exit" on the remote to get out of it. Does anyone have any suggestions to fix this? Should I call and ask for another replacement?
