    I am maxing out at about 6.5 Mbps on a 100 Mbit wired network, going from THD --> PC via https.

    Really? Isn't that is about 10Mbps. Should be about 10 times faster.

    How could you tell is was transferred at 9GB/hr? I only see 6-10mbps out of my THD.

    What software are you using 9.1 or 9.2J?

    Can you try the same thing using the HTTPS interface. Mozilla does a good job at showing the transfer rate for a quick test.

    Aha, finally someone else who uses a Netgear Powerline adapter. What speed does your adapter claim?

    Took 60min to transfer 90min of 6GB/hr show.

    S3 9.1, THD 9.2

    Can you try the same using the HTTPS interact to the THD from a PC?

    For TTG, I get 14-18 mbit/s over a hardwired connection, which is usually either slightly faster or slightly slower than realtime for HD material.

    What speed is the nic in the TiVo Series3? I have it hooked to a 10/100/1000 switch. My MacBook Pro is connected at 1000. How can I tell what the TiVo is connected at?

    I'm glad you asked that, because that particular show (series - The War PBS HD) is failing to transfer via normal TD TTG. Maybe I can do it that way and give you an answer as well.

    Thanks for the tip. :)

    Edit: No luck, Xfer to PC still fails using IE browser.

    Here's a sample datapoint:

    I have an S3, free TiVo Desktop 2.5, and a wired 100Mbps Ethernet network. The TiVo is separated from the computer by 1 router and 1 switch on my home network, all running at 100Mbps.

    I transferred an HD program of 1 hour 2 minutes in length from the S3 to my computer in 1 hour and 20 minutes.

    The file size on the computer is: 7,905,008,212 bytes or 7.36 gigabytes

    For 80 minutes or 4,800 seconds the math breaks down like this:

    1,646,876.71 bytes per second (roughly 13Mbps)
    1,608.28 kilobytes per second
    1.57 megabytes per second

    EDIT: Going by this formula:

    TTG transfer rate = (File size of .TiVo Recording in Bytes on your PC * 8) / (Minutes to Transfer Recording * 60) / 1000000

    I come up with 13.175

    How about multiplying the # of GB/hr by 2.2 to get close to the # of mbps. ;)

    My S3 is connected direct to the router, and I'm on a 'g'-connected computer.

    A 2.74 GB file took 28 minutes to download -- that's almost 6GB/hour.

    Mine claims 85 Mbps. They are all wired to 10/100 switches (Linksys and Apple Extreme).

    It's 10/100. Unfortunately, that'll be your bottleneck.

    There are two types of powerline adapters. There are the Homeplug AV and comparable models which claim 200+Mbps and provide 25-60+ Mbps usable throughput, depending on the conditions of the electric wires in your home.

    The second is the Homeplug 1.0 type which claim 85Mbps, and typically provide 10-20Mbps usable throughput, depending on the condition of your electrical wires.

    The rest of the throughput goes to error correction and other overhead, just as a 54Mbps wireless connection only provides 16-19Mbps of usable throughput.

    My simple test is connect to my S3 via the webpage:

    https://<my_tivo_ip>/nowplaying/index.html

    And download a show. ("Save as" via IE)

    I'm getting a steady 1.5 MB/Sec over wireless G (bridge).

    I used this equation for an HD transfer from my S3 to my Tivo HD. The 1 hour HD show was 6.47GB, and took 38 minutes to transfer. After the calculation, I came up with 22Mbps, or 2.75MB/sec.

    Both Tivo's are hooked up via ethernet to a Slingbox Turbo Powerline adapter, which is rated for up to 85Mbps.

    All in all, I'm very happy with a 38 minute transfer time for an HD show; not bad at all!

    As I am going through MRV in everyday life, anecdotally I think I am seeing some cleverness in transfer speed.

    I'd ask folks to look for:

    Faster transfer rate when watching the transferring program (hi def), esp. when not far from end of "buffer". Example: I've seen the rate go from ~1.1X before starting to watch program to ~1.5X while watching program.

    Min. transfer rates resulting in SD programs transferring @ 3-4X while HD programs transfer in the 1-1.5X range.

    The above refers to MRV between hi def TiVoes. S2s (240) as servers to S3/HD are much slower and rate depends heavily on USB-ethernet adapter model.

    I tried the same thing. My results were about 1.3 MB/Sec downloading a 3.x GB HD show on a G-network.

    It was interesting to see the data rate drop SIGNIFICANTLY unless both tuners were tuned to NON receiving stations. I have my TivoHD hooked up OTA and when both tuners were tuned to "non-stations" i was getting the 1300 KB/sec as reported by firefox.

    When tuned to a single HD station, the date rate dropped to ~850 KB/sec and tuning the second tuner to another HD stations the rate dropped further to ~730 KB/sec.

    I figure that translates into about 10.5 mb/s.... or just slightly slower than 802.11b (theoretically speaking of course).

    That's pretty lame if you ask me.
