5. Installs a fully functional cron setup for improved performance and logging. Creates all required directories and files, and installs a crondtab to do the following:

- Restart Tivowebplus every night at 3am CST to eliminate occasional problems that crop up with TWP.

- Create a tarball (archive) of your logs once/week, and save it in your root directory for easy FTP’ing. Helpful to have if something ever goes wrong with your Tivo, or you just want to explore your logs for well-defined time periods.

- Wipe your logs once/week (after archiving them) to keep them from getting to big and hindering performance. Also wipes the tarball archive above.

- Run fakecall every night at 3am.

- Reboot your Tivo twice/week at 3am. This cleans things out for better performance if you have several hacks running. Also restarts logs, and allows fakecall to reset the last successful call indicator, so your Tivo won't call home (fakecall doesn't update mfs entries without a reboot). This allows you to keep your phone line connected for PPV ordering or CallerID.

6. Searches for and removes MRV/HMO expiration certificates from MFS.

7. Makes a Backup of Your Season Passes and Wishlists. This is extremely useful if your drive ever fails, or you have to rehack your Tivo, upgrade to a new software version, or buy a new Tivo. Many thanks to agw who wrote the core tcl script that makes this feature possible.

8. Appends Your Crontab to Make a Weekly Backup of Your Season Passes and Wishlists. I always forget to make manual backups in TWP, and when I clobber one of my Tivos, I’m always restoring an outdated backup. This feature uses cron to make weekly backups and store them in /seasonpass-backups/backup. Be sure to frequently FTP the backups to your PC for safe keeping.

9. Adds or Removes Showcases and Yellow Stars. If your Tivo is hacked, you most likely don’t get Showcases and Yellow Stars anymore. The script asks you if you want them or not, and runs one of two tcl scripts that add or remove the MFS tokens that signal Tivo go give you showcases. If you select this, showcases should start showing up the following morning.

10. Updates the Profile to Easily Edit the Crontab. I added an alias to the .profile called “root” that opens up the crondtab (var/spool/cron/crontabs/root) in vi. I hated typing that whole long path every time I wanted to edit it. Just type “root” from bash to edit this file.

11. Installs NCID CallerID Application. Both the client and server are installed on your Tivo. Also, you can manually configure it to run the server on one Tivo and have it communicate with multiple Tivo clients. Other options can be tweaked to your taste. See the NCID website for details. The on-screen display program used by NDID does not work for Series 2.5 Tivos, so this feature gets skipped.

12. Installs USB 2.0 Drivers. First backs up original drivers to a folder called backups-orig. Installs the correct drivers based on the kernel version of your Tivo that’s detected by the script. Thanks to Jamie and Alldeadhomiez for making this possible, and for granting permission to use the drivers here. There's always a slight chance that replacing drivers will kill your connection, so be prepared to break out the serial cable or pull the drive. Adapters tested so far include: Netgear FA120, Linksys WUSB11, Airlink ASOHOUSB.

13. Confirms network settings are appropriate for MRV. Checks to see if your IP parameters are permanently set in MFS, and if not, will set them for you if you choose. This is required for MRV to work properly.

14. Installs "netperf" to measure network performance between multiple Tivos. Actually, it just configures netperf paramters in a series of aliases that let you easily test MRV speeds by typing a single word a the bash prompt.

15. Installs EndPad (Plus). Many thanks to Sanderton and Falcontx for their permission to use this fantastic tool. If you like EndPad (or even if you don’t), please consider making a donation to Cancer Research though this link, posted by Stuart Anderton, the author of EndPad.

16. Installs the joe Text Editor. For all who have cursed vi at one time or another, this is for you. It’s a bit more human friendly than vi.

17. Customizes Your Bash Prompt. This adds a descriptor to your bash prompt, which can be especially useful if you have multiple Tivos. There’s also an option to add the “TiVo colors” to the bash prompt. Here's what it looks like:
If you received your 6.2 image from a Tivo download and then hacked it using the Gunnyman guide, you most likely got theses certificates, which will stop MRV/HMO from working 180 days after the download occurred.

18. Keeps Your Hacks Out of /var. The /var partition is the equivalent of a Windows recycle bin, and occasionally your Tivo will decide to wipe everything in there. The problem is that many hacks are hardcoded to use /var, and will not work if stored anywhere else. All such hacks installed by the enhancements script are stored in /enhancements/varhacks. The script creates symlinks in /var that point to the corresponding hacks in /enhancments/varhacks. It also appends the author file with commands to recreate the symlinks if /var ever gets wiped. If you want to move other hacks out of var, copy them to /enhancements/varhacks, and then run the script called var-symlinks.

 

In other words, the Zipper is a method to hack your TiVo, while the Enhancement Script builds upon an already-hacked TiVo, regardless of the method originally used (such as PTVnet); the Zipper happens to include the Enhancement Script as part of the download.
