    A TrackTalk banner ad says "Behold the biggest, boldest box ever. Record 1,000 hours, 4 channels at once. The NEW TiVo Premiere XL4 DVR". What are they talking about? I thought the XL4 had 300 hours of capacity.

    1000 hours SD maybe, not HD. Or is there now some other recording format that uses less space? My upgraded 2TB Tivo regular Premiere says 318 HD hours or 2788 SD hours.

    Two disks + mpeg4 would do it in HD, but so far as I know TiVo doesn't sell two-disk XL4s. If they meant SD, why not quote the 2700 number rather than 1000?

    The XL4 can only record digital cable, so unlike the 2 tuner unit there is no quality selection for SD. On the 2 tuner unit they're quoting SD hours in the Basic quality from an analog station, which is only about 800MB per hour. Most digital cable channels are closer to 2-3GB per hour. So the 1,000 hour figure is about right for digital SD.

    Dan203 is correct. However, it is worth noting that you could get upwards of 750 hours HD if Comcast ever gets in the MPEG-4 game, as they will probably compress the sh*t out of it like they do now. Even Comcast's MPEG-2 HD bumps the hour capacity of the XL4 up quite a bit. I guess it's one upside to compressing the sh*t out of everything and having intermittent macro blocking and artificating issues due to compression.

    Yeah with them recording pure digital the hour estimates really vary from provider to provider. It really depends on the amount of compression your particular provide uses for a given channel.

    FIOS is going to be all over the place when they start doing channels that people actually watch in MPEG-4. One channel could use less than half of what another uses.

    i've compared dtv mpeg4 and comcast mpeg2 - it really doesn't appear to make that much of a difference overall on a 1tb drive. quality is comparable between the two, mpeg2 maybe a little better.

    It should be about 50%. MPEG-4 at 8mbps, MPEG-2 at 12mbps. Of course, it's hard to tell on different DVRs.

    My H.264 recordings range 8-9 Mbps

    While my MPEG-2 recordings range between 9 Mbps to 19 Mbps

    You're on FIOS? On Comcast, the MPEG-2 is pretty solid around 12mbps, since they triple channel. FIOS has a lot more room to play, since they're running 19mbps half-QAMs.

    No, I am on Cox Communications In Phoenix, AZ (hence CoxInPHX)

    Cox here is a 1GHz plant using SDV, and the HD Locals reach as high as 19Mbps so does Animal Planet HD & FXHD

    Here we have 28, H.264 channels,

    Wow. Jealous. Sort of. Except for the SDV part.
