Running bufferhack40a.tcl with Command Line Options
------------------------------------------------------

change to the directory that you placed bufferhack40a.tcl in

Then ./bufferhack40a.tcl

bufferhack40a Usage:

bufferhack40a.tcl <minutes of buffer> <(q)uiet mode/(s)ilent mode>

Example -

To give your tivo a 60 minute buffer of Live TV while watching all notifications:
./bufferhack40a.tcl 60

To give your tivo a 60 minute buffer of Live TV with ONLY ERRORS displayed on-screen (Quiet Mode):
./bufferhack40a.tcl 60 q

To give your tivo a 60 minute buffer of Live TV with NO SCREEN OUTPUT AT ALL (Silent Mode):
./bufferhack40a.tcl 60 s

type reboot

It looked like a simple procedure - what could go wrong?
After reading through the source code, looked safe enough to give it a shot.

Records were updated, typed 'reboot' from a serial telnet connection...
then I got:

=============
TiVo:/>reboot
flushing ide devices: hda
Restarting system.

Output enabled
Ram size = 32
Service number is 2640000F021E191.
What is password?
=============

OMIGOD!! password?? from who..what..where..??
I tried everything I knew:
<blank>, media access key, email address, service number, my regular password, Tivo2Go password, my cat's name.........

Ran out of ideas, so I pulled the plug and re-plugged.

Thank god, that worked
I'm ok now

but what the heck was that anyway?

and thank you for yours, and others, hard work.

That was the prom menu.
You probably hit enter on your keyboard early on while the system was booting, and you were connected via a serial cable.

Ah...yep, that's exactly what I did alright!
jeesh..operator error...as usual...

So THAT's what it takes to be a Diamond Member, eh?
Thanks for the quick (and precise!) reply.

First of all thanks for releasing bufferhack I really appreciate it. Is it possible to patch tivoapp to enable recording of audio only channels using the locations found here, while running the newest bufferhack? This is on version 6.2.

You're welcome.

Um, sure. I'm not exactly sure how this is a question for the bufferhack support thread.

This is on version 6.2.

Um... OK. You can patch tivoapp for a myriad of things. Almost all are mutually exclusive of each other. Any patches that you make other then bufferhack are not likely to interfere with the play bar modification made with bufferhack 2.x+

I just upgraded to 6.1 via slices, installed superpatch, AW init. All seemed well with the hacking. The last hack I applied was bufferhack4.0a and started having the DTivo reboot every 15 minutes or so. As you can see I'm getting a Tmk Fatal Error. I installed bufferhack with the command line option of 60. Installed fine.

I deleted my tivoapp and restored the backup tivoapp and the DTivo seems fine again. I did not try bufferhack4.0 or 4.0b on this system yet.

6.1 ?? I'm assuming it's 6.2, else I would have expected an error...Try running it in standard mode and look for any oddities.

As jeboo alluded to above, bufferhack 4.x is for 6.2+ as it says in the documentation and posts. Did you really try it on 6.1?

Moreover, there is more that gets modified then just the tivoapp. .brf files are modificed as well in place of mfs mods in past versions. If you did indeed replace your tivoapp, make sure you rerun whatever you ran to reset the brf values, THEN replace your tivoapp.

**rpl** · 05-28-2005, 01:24 PM

You guys are right of course it is 6.2. Sorry. Interesting on the .bfr files. I'll have to do a search and see if I can learn something. Reverted to the backup tivoapp file and I noticed my buffer stayed at 60 minutes. No reboots!

Since my 6.2 is working with a 60 minute buffer I'll just leave it alone, unless somebody else gets a reboot problem just consider this one a fluke.

Thanks and have a good holiday weekend

What you are seeing is the bufferhack without the playbar fix...While the bufferhack script does make a backup of the original brf, it does not have the ability to reinsert this brf. Its strange that you are getting consistent reboots. I'll check your error log and see if it makes sense.

**kcciti2** · 06-03-2005, 04:41 PM

There seems to be changes in the BRF file format in 7.1b that bufferhack 4.0b doesn't seem to handle. I had the issue and ended up just redoing my HD (losing my recordings, etc). Anyway, I kept a copy of the kernel log and hope this will help the development.

Here's the related thread.
