Well, that seems to be true. I will come back another time and explain it. Hope it will help.

This is a really cool hack, I love doing projects like this myself, but I usually run out of steam before I can finish.

what about writing your own bitstream to the blank DVD?

The problem I have with this entry is how it's presented in a context that gives the impression that we all didn't know you could tap bus traces. The actual entry is cool though.

This has already been done with the x360 by the way. There is even instructions for adding a second chip and custom firmware for certain drives. It can be done with any drive, there just isn't instructions for other models.

I think we all know this stuff, we just forget we learned it at some time.

What is this, slashdot? :P

Anyway, read the article darkuncle. dd will not give you every bit on a DVD, only the decoded bits. tmbinc is after *every* bit, including the sector headers, error correction, and sync signals. This hack is about as low level as you can get. Any lower are you're working with analog signals.

take a hint: this can be used to break disk copy protection schemes, which are nothing more than poorly formed disks used to confuse dvd players. dd just doesn't cut it.

unless I'm mistaken, you can already read every bit from a DVD (or any other block device) with dd(1) ... I'm using this right now to make bit-for-bit images of all my DVDs, storing the resulting ISOs on my storage array, mounting the ISOs over the network and playing them back with VLC. Voila; instant online DVD library.

dd if=/dev/rcd0c of=/storage/SomeDVD.iso bs=4096

(bs=2048 is standard; I'm experimenting to see which block size numbers give the best performance)

(Also, hackaday needs to toss their non-RFC compliant email address validation code - a plus sign ("+") in the userpart is perfectly valid, even though there's a depressing number of code libraries out there that are not compliant with the specs. See RFC768.)

steve.. r/c Resistor and capacitor hacks?! hah
okok, im not an idiot.. but radio control is boring. theres no brains to it.
its like…. attaching a hammer to an rc car and calling it a ‘bot. I commend your duct-tape engineering skills, but a robot maker you are not.
