    My Tivo just received the TTG update yet the software is still on v9.1...

    Question is will this update work without the most recent update of 9.2 or better ?

    To be honest, I had been wondering about that.

    I'd noticed it too but hadn't had time to do any exhaustive testing to see if it really was that way.

    The "sticky 30 second skip" thing was noted in a "9.1 Bug Fix Summary" thread.

    It's working just fine here with all machines on 9.1

    So I copied some shows from one S3 to another.

    The majority of copied shows were put into folders in the destination machine, just like they were in the source machine.

    But one set of shows (Rescue Me from F/X) wound up as individual shows at the destination, and won't move into a folder. I've tried turning folders on and off to see if that would work, but it doesn't.

    Anyone have any idea what happened, and how I can prevent this in the future?

    S3 MRV is SLOW. I can MRV s2 to s2 and even watch on the first level of FF.

    From S3 to S2, I can't even watch it for 10 minutes...

    S3<->S3 MRV is the fastest possible of all Tivos right now... under ideal conditions I can get up to 44 Mbps (20GB/hour).
    TivoPony already explained that S2<->S3 there are conversions taking place that demand CPU resources and really slow things down.

    How is S3 <--> HD ? That will be my situation

    THD units average only about 1/2 speed of S3 transfers (both for MRV & TTG). TivoPony also mentioned that was the case but that Tivo is still looking into it. So I think S3<->THD transfers are at best half the speed of S3<->S3 transfers. Under average conditions I get 20-30 Mbps (10-14 GB/hour) for S3<->S3, so I would guess THD<->S3 would be around 10-15 Mbps (5-7 GB/hour) on average - assuming wired connections, wireless could be much slower.

    Fine, but I think that sucks. So what, he explained why it sucks, it still sucks. My $700 dollar tivo runs worse than my free S2 after waiting a year for MRV.

    I can't use MRV S3 - S2. It needs to at least run real time. I don't buy that it isn't possible to implement MRV so that you don't have to sit there for 10 minutes of buffering before you can watch it over a 100 Meg wired network.... Bad implementation.

    and how is 44 MBPS good?? (And what are "ideal conditions..?") It's less than half the speed of the network connection!!

    I'm not sure about S3 to S2, but S2 to S3 runs slightly faster than real time for "High" quality recordings. This with the S2 and S3 both plugged into the same switch.

    20GB/hour is pretty good considering HD programs are typically 8GB/hour or less and is MUCH faster than any prior Tivo transfers. 100Mbps is theoretical max and doesn't account for real data rate transfers - a typical packet of data includes quite a bit of overhead so not all bits can be dedicated to video & audio data. Ideal conditions under which I achieved 44 Mbps (which obviously are not what one would normally operate under):
    1. All 4 tuners of my S3s tuned to channels I don't receive
    2. S3s wired together (cat6)
    3. Not watching until transfer completes
    Good is all relative - compared to S2 and THD units the S3 transfer rates are pretty darn good...
    Do I wish it could be much faster? Don't we all!!?

    I don't expect it to be fast, just real time so I can watch while it's transferring.

    You do expect it to be fast if you expect real time transfer speeds. Based on current home network topology, and the 3's 100 Mb maximum rate, your expectations of real time transfer speeds can not be met. There is not a system existing today which can meet 100 Mb speeds, even if you connect two machines together directly. It's just not going to happen.

    For one thing, there's a bunch of network overhead in every home network and networked machine. Cheap routers and hubs, unmanaged switches, TONS of packet collisions.

    How fast are you able to transfer large files between your computers?

    When transferring shows between my two S3's, I can begin watching in a few minutes after the transfer starts, and if I wait five minutes or so, I can skip commercials as well. That's with one wired and one wireless.

    I am, frankly, amazed that it works that quickly, all things considred.

    What do you think the bit rate is?


    What exactly did he say on that? Do you remember the post link?

    Here you go (there's also a little blurb on THD units being slower due to "system resources"):

    I've said several times that I'm talking about S3 --> S2, which means SD.

    Why in the world do you think it can't be done fast enough that I can watch it? I've been doing it for FIVE YEARS with my S2 TiVo's. The only TIVO that can't keep up is the S3..!

    Are you kidding me? I can watch SD content from a computer on the networkr. I can do the same for HD.

    In fact, I can stream SD content from the Internet. And from another S2 TiVo.

    If you cant watch SD transfers in realtime (even with the 'translation')- I think your not typical. Perhaps you have something in your network setup slowing stuff down, but also you might want to nicely contact tivopony or tivojerry or someone to pull your logs - maybe there's a situation at your house that they didn't run into before and they need to know about it to correct.

    I have 2 S3's and an S2 DVD-R unit (which generally behaved more sluggish than the S2 and S2dt i had before I got the 2 S3's). I can transfer SD from to and from the S2 well better than real time even when using the S2-DVR's 'extreme' bitrate setting. Between the S3's I can more SD and even HD faster than realtime.

    Maybe the S2-dvd-r is using same sort of encoding settings that hte S3's use and that's why it works well?

    I'm on a wired network. The S2 DVD-r doesn't have ethernet built in so I'm using an linksys usb dongle for that.

    Do you have any wireless adapters in play?
