s3tots will convert your unencrypted TY recordings into standard mpeg2 transport streams, in a single step.
s3tots works on all combinations of OTA, analog cable, digital cable, SD, HD, and even tivocast, but not Amazon unbox. (Unbox recordings seem to include extra macrovision(?) scrambling of the video&audio streams that I'm not interested in getting into.)
s3tots has a simple command line user interface just like tytompg. Typical usage is simply:
Output is to <show>.ts by default. Some switches:Example:Code:-y Allow overwrite of output file without confirmation, even if it already exists -i <file> Specify input ty/ty+/tmf file -o <file> Output .ts to specified file -c start,duration Only extract .ts from start thru start+duration time. Start and end are decimal numbers, units in seconds. -s <number> Skip <number> chunks on input before processing. Note: if input file is a .tmf file, this option will not work correctly -n <number> Process <number> chunks from input -t Omit PAT/PMT tables in generated .ts file (included by default)I've had success playing back transport streams with most media players, including xine, mplayer, vlc, and powerdvd. For some streams, xine&mplayer can screw up the a/v sync during playback, even though the sync is preserved during the decode process. powerdvd&vlc don't seem to share this problem.Code:% s3tots sell.ty s3tots: Copyright (c) 2004-2007 B.C. <firstname.lastname@example.org> Version 0.7, Source is sell.ty, dest is sell.ts TY set video,audio pid: 7c0,7c1.

If you're having trouble with a media player's ability to play .ts files, or with an authoring program's support of .ts, you may want to try converting the .ts to .mpg. I believe the best tool for this is videoredo as it also allows for frame accurate editing and can repair transmission problems in your stream, all without re-transcoding the streams.
s3tots tracks and reports on continuity errors, discontinuity flags, and warped PCR timestamps. You likely can safely ignore any such errors, so long as you process your resulting .ts file with a program such as videoredo. Otherwise, such errors likely are a sign that you have reception problems and you're best off re-recording your show.
Windows 32, linux-x86, linux-x86-64 binaries attached, as well as source.
Update: 1.4 version (source code only; as change vs 1.3 is only source code portability for osx).

Is this what I think it is ?
Does this mean I can take my recorded HD shows off of my s3 tivo and transfer them to my Unix fileserver, without DRM, and keep them forever, even if I throw away the tivo ?
Well, I don't know the legality - I mean, I am _paying for_ the cable TV, and I don't see any option possible to _pay more_ for it...
This is HUGE! I am going to buy an s3 tivo _today_ ... previously it was irrelevant because the shows were locked into a closed, proprietary system and could not be moved arbitrarily to whatever unix-based device I wanted to ...
Does tivo know how many people are disqualified from using their products because their products are "defective by design" ?
Ok, last question - does this work on _both_ the original s3 and the new "HD" tivo ? No problems using cable cards as the inputs ?
keep in mind that this will require a prom hack (hardware modification) and a software patch to disable encryption; shows recorded prior to this won't be extractable.
What is the track record for future tivo software updates/upgrades breaking this setup, should I dive into it ?
I am thinking of the recent iPhone situation where a number of third party apps stopped working due to a iPhone software update ...
I'd really like to buy a HD tivo and get this going (that is, the ability to actually archive shows, not just have them tenuously stored on a volatile, defective-by-design, closed, non-redundant system) but I don't want to invest the time and money if tivo will just break it next month...
If you ever get nervous about "patched" system software, you can always allow it to update to regular Tivo software.

As far as system software goes, with a little brain power one has so far been able to accept OS upgrades while preserving ones modifications. There are threads around that show how that's worked out. In summary there hasn't been an active countermeasure in that area either, but once in a while a few extra steps are required (such as extra changes to installSw.itcl).
http://tivodecode.sourceforge.net/ If you don't mind the extra encryption&decryption steps involved (they slow transfers down certainly), you may be OK with just that solution.
Ok, I am sorry to beat this to death, but now I am really confused ... about 6-7 months ago I asked this question:
(see third post in the thread - "what does this get me?")
And I was told that full-res, HD, non-DRM extraction from an S3/HD unit was not yet possible.
But you are saying that it has been around for over a year ... so either the answer I got in that thread was wrong, and full-HD, non-DRM extraction _was_ possible in early 2007
OR, s3tots is not what I think it is ...
I thought that the s3/HD encryption was different than previous models ?
The bottom line is, I want to offload (without DRM) full-res, HD copies of protected, premium cable TV channels (HDNet, MHD, HBO, etc.) ... am I understanding that that is possible now with an S3 or an HD tivo ?
It's a lot tivo CSRs claiming esata drive expansion wasn't possible until yesterday
The TY file format for s3s is new/incompatible from s1/s2' see my new development thread for an overview of that.
Seeing as I was one of the respondents in that thread, in my own defense I certainly wasn't aware of your great progress on decrypting the S3 transport streams at the time that was written.
FYI - TyTools works great for extracting files from an S3 Tivo without the previous limitations on file sizes for HD content as was previously experienced with the HDTivo. I believe there used to be a maximum number of FSIDs TyTools could extract before it quit. This does not to appear to be an issue with the S3 Tivos since I've been able to extract movies exceeding 25GB with no problem. However, FSIDs used to be limited to 512MB, IIRC. I've had FSIDs from an S3 Tivo be well over 1.5GB and there doesn't seem to be a consistent size for them anymore.
Please don't PM me or any other members looking for personal assistance. You'll do better by posting (after you've exhausted the search feature, of course) and taking advantage of the collective expertise of the membership instead of a single individual that may or may not be able to help you. Thank you and enjoy your stay at DDB!
