    Now that MRV is enabled for TiVoHD and S3 owners
    http://www.tivocommunity.com/tivo-vb/showthread.php?t=371193

    I'm curious how quickly you can transfer a HD recorded program. lets use a 1 hour program as our test. Start the transfer and start your stop watch. Once the show is fully transfered, stop your stopwatch and post your time here. Also let us know if you are on a wired or wireless network.

    Thanks!

    Yes, please share all.. I have not yet gotten home to test my s3 <-> s3 wired transfer speed, but here's hoping I can watch in real time!

    Maybe things will change later, but so far my S2's and my computer are not allowed to transfer HD programs from my S3, only SD. I get a message saying "Because the program is in HD format, it cannot be transferred to a non-HD Tivo", or something like that.

    My S3 is accepting and transferring a SD program from my pc at about twice real time. Its transferred about 30 minutes of the SD program in about 15 minutes.

    Edit: Now my pc will accept HD transfers. Just "happened"

    per TivoPony, they will not transcode the formats and as such, an S2 will never be able to pull HD content from an S3/THD. I had thought that you could use ttcb for hd content on the s3/thd though...

    of course, you could probably transcode the hd via a pc intermediate setup

    Just got through tranferring a 1/2 hour HD show from my S3 to my PC. It took about 50 minutes on my wired network. Now, transferring it back to the S3, it appears to be taking about the same time.

    I'm transferring and the speed is ridiculous. Transferring 1 hour HD show and it's telling me it's going to take 3.5 hours. I may be on a wireless-B network, but that should still be a sufficient speed to transfer at a much higher rate. I'm using TiVo wireless adapter, and computer is wired to the router. Both are in the same room, so signal is always excellent. Really angering me...

    *EDIT* I have an S3, not TiVo HD.

    I'm interested to see what it's like for G based speeds... anyone?

    I have wireless-g router and just transferred a 1/2 hour HD show from THD to S3. Unfortunately I decided to transfer a different 1/2 hour HD show the other direction at the same time. Each transfer took about 80 minutes (overlapped about 90%).

    Are you really disappointed? That seems plenty quick to me!

    HD is tranmissted at a theoretical max of 19.2MBPS, although most channels broadcast in the 10-14 MBPS range.

    802.11b is limited to around 3-5 MBPS (practical max), despite the optimistic 11MBPS designation.

    A one hour show WOULD transfer at no quicker than 3X realtime (show duration). By my quick fuzzy math.

    Time for a network upgrade? ;)

    You have to remember that transfer speeds will vary depending on your network topology. If you want the fastest transfer, you want your PC, router/switch, and Tivo all hardwired. If any link is wireless, that will be the bottleneck. If you have 802.11b anywhere in the link, everything will go to that speed.

    Remember that 802.11b is theoretical max at 11 Mbps. Typical is 4.5 Mbps. I've found a 1 hour Tivo HD file can be up to 9 GB. If I did my math correctly, that's 1.8 GB/hr. So 3.5 hours seems correct.

    I have my Tivos hardwired using Netgear Powerline adapters that work up to 80 Mbps. Those seem to work quite well.

    Sheesh - my first genuinely helpful post here in months, and I get upstaged. I should just retire.

    Is there any utility out there to figure out where your bottlenecks are and/or what transfer speeds you are getting? I have everything hardwired.

    Oldskoolboarder and ashu, thanks a lot for the number crunching. I guess I was under the assumption that it should be able to transfer HD content a lot faster. Guess I was wrong! I'm going to be moving to a new place in the next couple weeks or so, and that would have necessitated a network upgrade, anyway. So, looks like I'll be searching for a new G router. Any idea with a G router, how fast a recording SHOULD transfer, then?

    Anyone got Wireless N? I wonder what the speeds are like with N.

    I'm pretty certain the networking even on the S3 is CPU-bound. I've never seen greater than about 2.5X my regular S2, even before the 'official' MRV was turned on. The variety of MIPS processor in the S3 is still pretty slow, even for what was originally an $800 box.

    With the sheer size of some of those HiDef recordings, it's going to take a long time for transfers.

    too bad there wasn't a way to stream the video from box to box instead of having to transfer the entire video.

    The second one-hour program took 1 hour 40 minutes to transfer. And that was SD at Best Quality over a wired network.

    How did you determine that its CPU bound on the S3?

    f you're looking into upgrading your network, you should look into a -n network...of course I think that Tivo's are only -g capable.

    That said, you can still get a -n network going.... you just have to put the router next to the Tivo and hard wire the tivo. That way all other computers will be on speedy -n wireless, and the Tivo will have a speedy wired connection.

    If you try to go -n and mix a -g card somewhere in the mix (like the Tivo) you're going to slow down the whole -n network. -n doesn't like mixing flavors. Hardwiring the Tivo avoids that.
