You're missing the point... it ignores the SIGNATURE. Once you get it to do that, you can then modify/remove values from the DRM object without causing tivoapp to object. Otherwise, it would compare the values to the signature and invalidate the recording if they don't match. But simply causing the signature to be ignored without making any changes does nothing at all.
Also, stuff you download from other sources (Amazon, VOD, etc) has an additional layer of encryption & rules applied to it that your regular recorded stuff does not. I've not examined the effect of changing DRM values on those types of recordings.
And finally, on another note... I don't know why people are so keen to remove the Tivo drive or otherwise connect it to a PC in order to complete an upgrade. You can do the same thing from a telnet session while the Tivo is running without ever touching the drive. I posted a high-level overview of how I handle upgrades here.
I did the tivoapp hacks by renaming the file in telnet, creating a copy of that file with the tivoapp name, editing that new file and rebooting. (being that I pretty much use windows, it's not normally possible to rename a working file while it's active... then creating a copy of the working file with the old name [now inactive so it can be edited], just never crossed my mind!) The hacks work fine.
I needed to pull the drive because I had no way to load MFS_FTP or Tivotools. Once I had the .RAR files in the proper places, I booted the tivo and went back into telnet and did the rest from there. I can now FTP into the tivo root and download/upload and modify the files that way.
I also "kind of" have MFS_FTP working. I can connect, list, but the second I try to download it kills the connection. So I have to figure out what is wrong with that. But that's for another topic, I think I am getting closer to the solution. This morning I couldn't even connect. Once I get that working and can download shows, I want to try and install TivowebPlus. But progress in small steps. And at least next time I can use the terminal to get the shell access, and FTP to edit/upload whatever needs to be edited.
And yes, being that I haven't worked in the Linux environment for nearly a year probably made things a bit more challenging.

1. It was easier. With the primary drives being external to the TiVos and a tarball with all the hacks just sitting and waiting to transfer, it only took a minute to re-hack the Tivo by pulling the drive, plus boot times, of course.
2. Sometimes /var gets wiped. In or outside of an upgrade, having a ready-and-waiting tarball made replacing /var oh so much easier, and increased the attractiveness of #1 as a side benefit.
3. Before I increased the size of the partitions in order to implement mike_s' suggestions, it was not uncommon for me to run out of space on the root partition when upgrading, especially when hacking tivoapp.
4. It is fairly difficult to over-estimate the value of having a full blown Linux machine managing the drive when upgrading it rather than the highly limited OS found on the TiVo.

Is there an 11.0L?I noticed my Tivo isn't connecting to the Tivo Central anymore...
