Dtivo Video extraction, splitting, and muxing - Scripts, programs, and How-to's only

[Yzo]

Noxin,

Excellent script. I've used it a couple times and find it a very easy way to extract programs from my DTiVo.

I do however have a suggestion. On or about line 151, the script expects that tydemux will return an A/V offset that is early. I'm referring to the following:

[snip]
$indexofoffset = index($demuxout,"early use -O");
$indexofoffset = $indexofoffset + 12;
$offset = substr($demuxout,$indexofoffset);
[/snip]

Unfortunately, for some of my programs, tydemux returns an A/V offset that is late, i.e.: "A/V Sync Offset: -06ms (i.e. audio plays 006ms late use -O 006 in mplex)"

This causes the script to pass a bad offset to mplex and the process is broken from that point on. To fix this, I changed line 151 to disregard the early/late portion and use "use -O" instead. It's still a unique portion of the line so index() should still work as such:

$indexofoffset = index($demuxout,"use -O");
$indexofoffset = $indexofoffset + 7;
$offset = substr($demuxout,$indexofoffset);

I ran a couple tests and this seems to do the trick.

A FAQ with detailed information about installation and basic usage for TyTool has been created and posted both here on DealDB at http://www.dealdatabase.com/forum/sh...581#post156581.

It can also be found on the www.TyTool.com website.

For any initial questions etc... Please refer to the FAQ first, before posting or PM'ing.

Okay, well, the original post says DTiVo, but there are no current guides for the standalones and no other guide stickies, so here we stand. This guide can also apply to the DTiVos somewhat, but it has only been tested on a PTV100.

The original purpose was to capture video from VHS using the TiVo, but it can apply to any situation where your video source is of poor quality, such as distant or overlapping stations in fringe areas, crummy cable service providers, etc.

As usual, if anyone has suggestions, feel free to send me a PM.

What is needed:


TyTool 10r4
mfs-utils 2006-05-03
tivopart 2004-05-30
A Linux distro such as MFS Tools or Fedora Core MFS Tools already has fs-utils and tivopart built in, so you can skip those if you go that route.
bbTOOLS v1.9
VideoReDo v2.2.1.445
Audacity if you want to clean up crummy tape hiss or motor noise, etc[/URL]
Toolame 0.2k to reencode from Audacity
IfoEdit v0.971

1. Put the TiVo drive into your work machine. If you've never done this before, read the Hinsdale Howto and BACK THAT THING UP FIRST!!!

The name of this thread is:

Dtivo Video extraction, splitting, and muxing - Scripts, programs, and How-to's only

The first few are about Dtivo, but the rest get into TyTool and stand alone stuff.

PLEASE -- I have .ty files on my computer that I can't do anything with. How do I make movies out of them? Do I transfer via another method to convert them strait into .mpg's? (I keep getting an error about the first 10 blocks).

From what I am getting...I have to get my DTIVO to stop encrypting the movies, then I can use TyTool to move the stream, then convert it to .mpg.
Is this correct?

tks

[artships]

Yes. So, read http://dealdatabase.com/forum/showthread.php?t=31213 and then move-on with Tytool.

If you are an S2 user with Software Version 6.2, type this command:

Code:
echo -ne "\x3C\x02\x00\x00" | dd conv=notrunc of=tivoapp bs=1 seek=10705308

So, I am not uploading any more hack code, just editing existing TIVO code (after making a backup copy), right?

anyone know how to turn the encryption off for version 6.3d-01-2-357?

that threads does not deal with my version of 6.3d at all.

I'll ask again...has anyone turned off encryption with 6.3d?

[jt1134]

Yes it does. The patch locations for 6.3d are the same as a, b, and c.

Notice from that thread : Nocso (courtesy of 7.1 -- for ALL 6.3 versions)
The only thing it doesn't apply to is the new 6.3e software.

So, to answer your question: has anyone turned off encryption with 6.3d?
Yes, I have. And I linked you to the info I used.

I respect your opinion and I tried and it said my version was not supported

[jt1134]

I tried and it said my version was not supported

I assume this means you tried superpatch. You'll need to update that script with the latest patch to use it with any 6.3 flavor. Here's a command line patch based on the info cheer posted :

mount -o remount,rw /
mv tivoapp tivoapp.orig
cp tivoapp.orig tivoapp
chmod 755 tivoapp
echo -ne "\x3c\x02\x00\x00" | dd conv=notrunc of=tivoapp bs=1 seek=1602412
sync
mount -o remount,ro /
reboot

so do this and thats all?

[jt1134]

Yep. All that will do is disable encryption on new recordings.

[jordan13402g]

tried it but it said it couldnt find the tivoapp file....is there a particular directory I need to be in? like /var/hack?
