Accessing TED talks or other Apps will disable Closed Captioning on a STB running 2.3, quick resolution is to reboot your box or disable and re-enable CC again
what type of issue? pixelating & freezing ?if your LIVE TV is ok and only your VOD is freezingm Make sure no P2P is running, if you have your itunes running backup on icloud could cause VOD freezing as upstream kills VOD packets
