    Exuberance slams into reality. :eek:

    How's navigating the remote DVRs' NPL using the S3 and HD?

    Just got TTG working here and the speeds are very disappointing. I was hoping that S3 would be much faster at transferring than the S2 since it should not be CPU bound for network - has a built in ethernet port and I assume hardware ethernet chipset. However, transferring a 30 minute SD show is taking 14 minutes over a 1000 MBPS end to end network..

    Yeah, your best bet is to hardwire. Typical 11n rates MAY go to 150 Mbps, if you're lucky. But if you have any legacy wireless (11b, 11g, 11a) they system will use the lowest common denominator. AND you will only get 11n rates if both the router and client have 11n. As was said, I don't know of any 11n client for Tivo. Even if you wire an 11n router, the wired link can only be as fast as Fast Ethernet which is 100 Mb. 100 Mb is line rate and doesn't include overhead so actual transfer speeds will be less than 100 Mb.

    yeah, it's a bit confusing and misleading when trying to figure out actual rates.

    OOORRRRRR you could hardwire the TiVo to an N Bridge (the cheapest way to go about it would be to find an N router (get two - one main and one for the TiVo etc in the Home Theater area) that can do bridging.

    That would be ... wait for it, wait for it ... an Ultimate Wireless Network(2)! ;)

    (see my signature - I use 4 G routers as bridges homewide - every device is 'wired')

    Not fast, but a lot quicker than the slow speed that my S2's had been reduced to by 9.1. Takes it about a second, maybe 2, to draw the screen as you page thru the remote NLP.

    Is 9.2 any better on the S2 than 9.1 was?

    You have to hack your box and watch 'top' while you transfer something.
    I'm downloading with TySuiteJ right now, with two SD shows recording on the S3 tuners, and playing back another SD show. The playback is stuttering and pausing-resuming badly because the S3 CPU can't keep up.

    Is G really that much better than N in this situation? I mean, isn't the TiVo also limited by how fast it can upload the information onto the network, anyway? Also, my laptop doesn't have an N card in it, only G, and I'd rather not spend the money to upgrade both that and my desktop to accept N speeds. I just figure, if I can get HD programs onto my computer at around 2X (obviously faster is better), and G can manage that, I'll be happy.

    Has anyone been able to do MRV for a HD show (say ~7GB for an 1 hr show) between an S3 and Tivo HD on a wired network in real time? meaning start transfer and watch right away. Is it possible to skip commercial and jump ahead? How much buffer does one need to do that?

    Exactly. An 'N' network won't show any improvement over a 'G' network for Tivo transfers. In fact, a good 'B' network might be enough, as long as you don't have any other wireless devices on the LAN.

    So are you getting max transfer rates no better than around 10 or 12mbps on the hi def TiVoes? Wired or wireless?

    Don't have 9.2 on the S2's (9.2 is only for the S3's, right?)
    While the S3 (using 9.2) can look at the S2's menus fairly quickly, all my S2's are still really slow looking at both S2's & my S3 remote NPL.

    The S2's are still as horribly slow as ever when looking at a remote NPL list and actually selecting a show. When doing that it still takes more than 10 seconds of "Please Wait" until it brings up the show's info screen with the "transfer this program" selection.

    The S3, on the other hand, not only does all the S2 NLP lists faster but is very quick to bring up the show info screen when selecting a show to transfer.

    IOW, if you want speed, use the S3 to bring shows from S2's, because its much much faster. S2's take a long time to navigate remote NPL's on both S2's and S3's.

    Now if they could just fix 9.1.

    Oh, I see, I'm probably getting 4.5 to 5 mbps right now, but with a G I could get at least double that, and that would cut down on time. What I don't understand, then, is why there is a theoretical max and a typical. Shouldn't a router work at its max? What's keeping it from doing around 11 mbps?

    I'm getting a disappointing speed. It took just over 3 hours to transfer a 2.5 hour HD show (around 13GB). Then it took <30 mins to xfer that show over the same wired network to another computer.

    Oh well, I can queue them up and archive some stuff overnight. Is this the speed I should expect though? Why is it so slow?

    As oldskoolboarder and mikesay98 noted, I've also never seen more than about 4.5mbps.
    I've heard you can replace the network drivers, and upgrade your wiring and router to support "Jumbo" frames to improve (wired) throughput. But I've never actually done it.

    I got an average of about 12 Mbps. Took 75 minutes to transfer a 64 minute HD file. This is on wireless G network where the TiVo is only about 25 feet away from the router though, and in the same room.

    Guys, going to "properties" on Tivo Desktop, then "performance " , we can set maximum cache size and activity level. My set was 10 MB and I changed to 300MB. Does it make any difference on the transfer time ? I changed when I had already started the transfer and I don't know if the new setting is being used. Didn't notice any difference and my G network , with nothing below G speed, should allow much faster speed. Estimated : 6 hours for a 2 hours HD movie (18 GB).

    Any Thoughts ?

    Ooops. :eek:

    Well maybe all this transfer and navigation stuff will get better in future releases for all platforms. Its all pretty new at this point.

    I am very disappointed at the S3 platform speeds observed so far. :thumbsdown: :thumbsdown: :thumbsdown:

    For me, The S2s may just become servers to Series3 platforms over time anyway. (And maybe that time will be accelerated. ;) )

    Is what you are doing an accurate reflection of TiVo's implementation and can we confidently relate the results (ie. CPU bound/bit rates) to TiVo's official feature?
