Hello!
Well the other day I had programing up until 7/7 in my subscribed 3.0 Philips SA. that night my Tivo SA turned to the Discover channel and was downloading schedule data over that broadcast. Afterwards it showed that I had program data to 7/12. 5 days of data.
Has anyone looked at how this data is being transmitted?
The data must be very full so Digital cable users with hundreds of channels could load programming. i only have 75 channels.
So does my Tivo pick and choose what data it retrieves, or does it swallow the whole linup and just filter it down.
Since it is one way, can non subscribed Tivos w/ 3.0 be made to DLoad this data?
I'm not a Perl, TCL Linux guy so I'd have no idea how to research this.
Thanks
Jerry

If this (hypothetically) became a problem, all TiVo has to do is encrypt the transmisson, and issue the keys via dial-up.
I'd be interested in finding out more how they do it. If you could actually _generate_ that type of data, maybe you could use it to transfer data between TiVos throughout your home using nothing more than some RF cables :)

If anyone was smart (Stupid unough) to actually post a way to make the stand alone work without the phone line, and just use the data downloand at 4:00 am from the discovery channel, they would undermine the ENTIRE Tivo service....I give it a matter of a few weeks untill this happens...in a selective way....
When I say "selective way", you could be aible to steal service, if you get the TRUE discovery channel feed at 4:00 am.
Unfortunatly for you, and GOOD for Tivo is the fact that MOST local cable co's "capture the feed" of the discovery channel and send thier own "infomercials!!!", AND block THE PAID STUFF, SO YOU HAVE LESS THAN 50 % TO EVEN GET THE DISCOVERY GUIDE DATA from your piece of shit local cable company :(((
So you can't get the push data......This cuts both ways, as they have to continue to send guide data over modem.....
Time will tell...

Someone on one of the other forums posted that the stream is encrypted. What happens is your Tivo downloads the steam and then during the nightly call in retrieves a key to decode the downloaded data. No way to make an unsub'ed Tivo utilize this data unless you can figure out how to generate the key.

Well,
My Tivo SA is not connected to the phone line. I only connect it once a week or so to get my schedules. The last time i did it it said i had data to 7/7. When it made that evenings DL from the Discovery channel it went to 7/12. Since I have not reconnected the phone line since then it still shows data to 7/12. Interestingly it does not look as if my TV even changed the channel since then to DISCOVER. So if it does not have a key, or downloaded "script" to record and decode the Discover channel at 4AM then it doesn't appear it even wastes its time.
This is interesting since once i get my own data running i didn't want to have to remove the DISCOVER channel.
I think those who can find the script and see what it is doing would find some interesting automation.

Appearantly Dish Network is sending down the Tivo slices via the Discovery Channel. I tuned into it about 3:30am (Central Time) last night and it showed some weird stuff and a scrolling message that said something along the lines of the channel being provided by the Tivo service and it was not an error. This happened on all of my Dish Network recievers, including those not connected to a Tivo.
The next step is to figure out how to break the encryption. I do worry though that this type of download would allow Tivo to update anything they wanted.
