TiVo OTA NetFlix Bufferiing issues Please Help.

Is it normal? This red screen of death this buffering wheel that stops what you're watching and tries to catch up.



Here's what I'm running: 22.47 Mbps., Motorola SPV5121 Cable Modem, Linksys N Router WRT160N V2, 75% signal, TiVo Series5 20.4.5.c-USA.



Any suggestions?
