Mayweather vs Pacquiao PPV (Time Warner Cable)

I ordered the Mayweather vs Pacquiao PPV via telephone. The lady I spoke with told me to tune in to channel 651 during the fight. I tuned into channel 651 and I get an error like "Channel not included in your cable card, please contact your cable provider for more information." I was wondering if anyone has any previous experience ordering PPVs on TWC and whether or not I'll be able to watch the fight on TiVo or have to get a separate set top box. I am using the TiVo Roamio Plus.
