Tivo 2 Tivo transfer speed?

How fast should one expect transfer of a recording on one Tivo to
another be using USB adapters with wired Ethernet between two series 2
units that are not otherwise recording or playing? Both Tivo units have
been upgraded with 7200 RPM Hitachi drives.

I have to wait for a several minutes to start playing, if I want to
program to play without stopping.

Is there any practical solution to this problem?

I have 2 USB Gigabit adapters wired back to back. The MTU is set
at 9000. It takes about 10 minutes to transfer a 60 minute show.

Just for clarification... I have 2 DTV Tivos. Each one has been
hacked to allow networking. Each one has a USB Gigabit adapter
( airlink from frys... wired adapters ) and the link has been
setup in tivo so that the MTU uses 9000 byte 'jumbo' frames.
You have to get / find Airlink, USB Gigabit Tivo drivers... they
don't come by default... if you can figure out how to hack your
DTV Tivo, you can find the gigabit drivers there....

This not not a normal setup or one for the average guy.... It
is easy to do if you have any experience hacking your tivo.
Just takes a bit of ifconfig knowlege ( command to setup
the network interfaces on a linux box )

Jack,

Thanks for your response. It takes me about 70 min to transfer an hour
show.

If I understand you correctly, you have a gigabit network adapter
plugged into the USB port of each Tivo unit and the adapters are
connected with a cross-over cable. Right?

I'm using two Linksys 10/100 adapters connected to my home 10/100
network. There are 10 TCP devices on the network, but not all that much
traffic, so I don't think congestion is an issue.

I was under the impression that my Tivo units were using ver 1 USB,
which would effectively limit throughput to something less than what the
10/100 adapters would support. Is this assumption correct? One of my
units is a Sony Series 2 and the other is a Tivo Series 2 that I got
about 2 yr ago.

Can I assume your Tivo units are equipped with ver2 USB? Otherwise,
please educate me as to why your gigabit adapters can transfer a 60 min
show in 10 min.

Jack,

Sorry, I didn't read your follow-up post until after responding to your
initial reply.

I now better understand how you're getting such fast transfer.

About your hack, my knowledge of ifconfig and Linux is limited, but I do
tinker a little. One of the PCs on my network runs Red Hat that I
installed with the hope of spending some time learning Linux, but that
has turned out to be more of a hope than a reality.

How difficult (and successful) is it to modify the USB port on Tivo
units like I have?

Peter,

Thanks for the info.

Is there a hack available that would speed up the USB port on a Series 2
Tivo?

Series 2 networking and DirecTivo networking are not comparable.

One can expect Series 2 transfer to run on the order of realtime. An
hour of programming might take an hour to transfer, or might take 40
minutes. It largely depends on what else the Series 2 is doing at the
time.

Most of the S2 Tivos have 2.0 USB Ports.... if they are
running the 1.1 type drivers they will run at the slower
speeds... but the ports themselves are 2.0 ports.

My SA S2 tivo that I use for some testing has 2.0 USB ports.

I get all my driver updates from
http://www.dealdatabase.com/forum/
I haven't updated my stuff in a few months. I'm sure
that they are still talked about over there.

Jack,

Thanks for the link to dealdatabase. Lots of good stuff there. I also
picked up three of the Airlink Gigabit adapters from Fry - can't beat
$10 for an USB adapter.

I have to do some more reading on dealdatabase to see what(if?) I can do
to speed up transfer between my two Series 2 Tivo units.

I understand networking with your direct Tivo units is not the same as
with my Series 2 units, and it is not clear to me at this point if I can
actually improve the transfer rate to much better than realtime. What
is your opinion?

Not sure if these Airlink's will work with the series two tivo box.

http://customersupport.tivo.com/know...lic/tv2183.htm shows
supported wired adapters, and it may need to be hacked to get the drivers to
work.
For all I know the adapter will work just fine.
When I looked before, I did not see any gigabit support.

I have 3 Tivo's
2 x Pioneer DVD 810h
1 x Series 2 (first gen).

All are networked with the Linksys USB 2.0 wired 100BaseT adapters.

The only hack I have was to replace the tiny 80GB disks with 300GB disks.

I record nearly everything in HIGH mode (not BEST). An hour program does
indeed transfer in 10 minutes or so.

The start playing comes up, and by the first commercial set, The
transfer is almost complete.

BEST mode takes a VERY LONG time to transfer. So long, I do not record
in BEST mode anymore. You may want to think about the same.
I keep tons of stuff on my tivos for months and this gives me a way to
move them around.
