I'm currently trying to transfer between a laptop and a series2 Tivo. The tranfers have all failed before the entire movie was transfered. I encoded the movie to mpeg2 so that the only processing necessary is the transfer.
I am using a Linksys class b USB adapter on the Tivo and builtin class g on the laptop. If the transer could resume I suppose it might complete eventually; but since that's not an option right now I'm considering another one.
My ethernet service is DSL and the wireless-gateway/router is in my office - one floor up and 2 rooms over from the Tivo. Wireless signal strength is excellent, but it too far for a cable even without the intervening walls and floor.
Can someone with more experience than I have with pyTivo tell me if they think the following might work? Could I run a DNS server on my laptop and run a cable between the RJ45 ports on the laptop and the Tivo? Basically just plug it in for an hour or so to transfer the video with a 100 Mb/s connection and then go back to the wireless network for the day to day scheduling and updates?
You wouldn't need a DNS server at all but I think you are thinking about a DHCP server to give the Tivo an IP automatically. That wouldn't be necessary as you could just hard code your Tivo to an IP (say 192.168.2.1) and your laptop NIC to 192.168.2.2 (with a 255.255.255.0 subnet mask) and they should talk fine and provide your hard wired method of transfer.
Make sure you either use a cross-over cable or a switch between them if your laptop doesn't do auto-mdi/mdi-x and crossover for you. I am almost positive the S2 nic isn't new enough to do auto-mdi/mdi-x.
A good step on troubleshooting your wireless connection(s) between your laptop and your Tivo is to type:
ping -t tivoipaddress
on your laptop substituting of course the IP of your tivo and watch for big packet loss. The packets should *mostly* be solid and drop very few packets but if you drop a decent amount, say 10-20 in a row, then the transfer could easily be canceled.
Also, does the transfer stop in the same place for the same file? This could indicate an error in the file and not a transport issue.
I did finally get a successful transfer. Part of it may have been I was still using files from last July; I'm using a Jan 2009 release now.
Wireless laptop to wireless Tivo took 21 hours for a 1.75 hour mpg2 file(3.4Gb). I tried again with a PC directly connected to the router/wireless hub and managed 3 hours transfer time for a 700Mb avi file.
I didn't try the direct connection yet; I'm going to try upgrading the Tivo from B to G on the wireless adapter and see if that improves things enough to actually transfer faster than I can watch. If that works I'll be happy doing that and not need to worry about directly connecting laptop and Tivo. Although if I do test it I'll let you know how fast the transfer is there.
Anyway, I think I have a handle on this thing now. Thanks for the help.
