    we have two TiVo HD's and a Premiere. All have cable cards from Cox Communications.
    Cox is beginning to implement MPG4 cable STB's.
    Will we need new cable cards? Will we need new Tivo's?
    Can Tivos do mpg 4

    I was wondering the same, if the Premiere tuners were capable of decoding MPEG-4 video. After reading the following article:
    Cox To Add Up To 30 HD MPEG-4 Channels To 'Advanced TV Plus' Tier

    But Cox has been talking about deploying MPEG-4 since 2007:

    According to the specs of the Broadcom BCM7413 chipset used in the Premiere:
    Advanced multi-format decoder supporting the following:
    - HD/SD H.264/AVC Main and High Profile to Level 4.1 (HD), Level 3.1 (SD)
    - HD/SD AVS Jizhun Profile Levels 2.0, 4.0, and 6.0 (720p and 1080i for HDTV)
    - VC-1 Advanced Profile @ Level 3, Simple and Main Profile
    - HD/SD MPEG-2 Main Profile at Main and High levels
    - SD MPEG-4 P2 SP/ASP
    - HD DivX® 3.11/4/5/6

    These MPEG-4 HD channels would be the "Plus Package" channels and are also allocated to the frequency spectrum between 860MHz-1GHz. The "Plus Package" channels are currently only available with the Cox Trio Whole Home DVR Cisco equipment. I believe the "Plus Package" channels are currently MPEG-2.

    So far Cox has not allowed the "Plus Package" channels on a CableCARD UDCP or even Cox's own Motorola capable receivers, with the exception of a few reports out of Orange County, CA. Member moyekj is one such report.

    Currently the Plus Package channels are: HUB HD, DIY HD, Outdoor Channel HD, Cooking Channel HD, SWRV HD Addt'l HBOs HD, Addt'l SHOs HD, Addt'l Starz HD, and Addt'l Cinemax HD.

    All the Series 3+ TiVos can theoretically handle MPEG4. However, they may need a software update. And I'm somewhat skeptical that TiVo will do any more updates for the Series 3. :(

    In Australia and New Zealand, they have TiVos with the same hardware as a TiVo HD, but different software (11.3), and those TiVos actually do handle MPEG4. AFAIK no U.S. cable provider is using it yet.

    You shouldn't need new CableCards.

    The OP asked a really interesting question. If the S3 can handle MPEG4, I'm curious why there has been a three-year process to get an MPEG4-compatible HDDirecTiVo to market. I assumed that it was more than just software issues. (But I'm not an engineer or a programmer, just a TiVo user.)

    If this move to MPEG4 is the shape of things to come, though, TiVo is going to have to come up with a good solution.
