Advanced Configuration

Network Transfer Options

Tytool can transfer contents from the TiVo in three formats determined by the settings in the File pull-down menu.

Selecting Vsplit mode will cause TyTool to split the content into separate audio and video streams and save them into separate files.  Note all synchronization information between the audio and video streams will be permanently lost during this operation.  The video file will be given a .m2v extension.  The audio file will be given an extension of .m2a or .mpa, depending upon the naming settings in the Options pull-down menu.  Once the download is complete, the user may edit the audio and video separately with the editing software of his choice.

Selecting TyStream mode will cause TyTool to transfer the content directly to the hard drive with no processing.  The resultant .ty file is in the same format as found on the TiVo.  Because there is no additional processing, this is the fastest means of transferring the content from the TiVo.  It is also generally speaking the best compromise between flexibility, simplicity of editing for the user, and speed.  If the user intends to edit out sections of the content or add chapter markings, this is the preferred setting.

Finally, selecting Multiplex mode will cause TyTool to convert the content into either a DVD or VCD format, depending upon the MUX settings in the Options pull-down menu.  This is a "quick and dirty" means of getting a program onto a DVD or VCD.  The resulting file may be imported directly into DVD creation software, commercials and all and with no chapter markers, to be burned to DVD or VCD.

GUI Options

Turning on the Make .TXT Files option will cause TyTool to create a text file while it does its processing.  This option is intended primarily for troubleshooting purposes, and the user should ordinarily leave it off.

The verbose level (0-3) determines how much processing data is placed in the .txt file.

Level 0 == Off.  If all goes well you see the data explosion at the top, the source type and the audio information etc..., followed by the position tick markers.  Each '.' character equals 10 128k chunks from the source file.  Every 100 chunks you get a numeric display of what chunk you were at - usefull when looking for bugs/problems/crash points/etc....  For instance this:

......... 100......... 200..

Means that 220 total chunks from the file have been processed.

Level 1 == Simple structural/splitting information is printed. The major lines are:

1- Dumping a 'too early' audio packet. => Record keeping that it found an audio record before the first I-Frame and had to deal with it.  These only appear at the very start.

2- checkNumRecs: Number of Records: - The results of the "is this unscrambled" check.  Each line is the display/decode of the first 4 bytes in each chunk.

Level 2 == Basically dump everything up to and including the multiplex level.  There is a wild ton of information in this level - way to much to try and explain.  What I will say is that I spend a great deal of time using grep when I work on the log files at the level.

Included is the frame order that was found, the GOPs, the PTS timestamps for both audio and video, etc...

Level 3 == Everything that is part of level 2 and the information found directly inside each of the SEQ/GOP/audio/video/etc...  MPEG-2 headers. A 1 hour/1gig stream produced upwards of 500meg of text in the output file when running in this mode.

So what should people use? Level 0 all day every day.  That is all that is needed 99.9% of the time.  If they run into a problem level 1.  Level 2 only when requested by me so I can see what the error they are running into is.  Level 3 isn't something I even use anymore.  It was needed at the time but now not so much.

MUX Options

The MUX settings under the Options pull-down menu are only relevant when TyTool is performing a Mux operation, either selected manually in the File pull-down menu or automatically when downloading the content if the user has selected Multiplex mode as the Network transfer option in the File pull-down menu.
