In October 2014, Comcast will transition its system in Augusta, Georgia, from MPEG2 format to MPEG4. This transition means that cable channels in this region will not be viewable on older equipment that is incompatible with the new format.
Roamio and Premiere units are ready to tune – having already cut their teeth on smaller scale channel conversions on Cox and FiOS. Unfortunately, TiVo Stream and Roamio Pro/Plus transcoding won’t be ready until 2015.
Streaming functionality will return in early 2015, when a software update that provides compatibility with MPEG4 will be released.
Sadly, due to innate hardware limitations, TiVo Series 1, 2, and 3/HD owners are mostly out of luck. And those in markets with MPEG4 cable programming are advised to upgrade to a newer TiVo or cable company-provided set-top.
