Just patched & tried out the 812S- not good- Comments appreciated

Got my Liteon SOHW-812S today, installed and Patched using Omnipatcher. Used the VS04 patched firmware. Bumped speeds on MCC01Rg20, and ProDiscS03, up from 4X to 8X to test out. Checked all boxes in the lower section.

Opened DVD decryptor and here is the log from the burn:

During the burn I had several instances where the device buffer would fluctuate abruptly say between 46% and back up to 99%. During these times the burner LED would pass from red to orange and back.

Results on my Sony standalone player: Got the FBI warning screen but that’s about all. Said disc was dirty.

Came back to try the DVD in the computer, wouldn’t play either.

Looking to hear what I may have done wrong here.
Should I only be using DVD+R’s? I have used almost exclusively -R’s on my DRU-500AX for the last year or so because they play on more standalones.

Did I expect too much on the speed?

All comments welcome & appreciated.

Here is the Kprobe about first 50% of the disc. Too bad I don’t know how to read this yet. :sad:

Second try: Used Verbatim dvd-r 4x, MCC01Rg20;

Got the same device buffer fluctuations, though I only attempted 6X on this go round. Burn time about 10 minutes. I expected SSDD (same stuff, different disc) but this time it played ( i jumped around the disc but it seemed okay) in my Sony dvd player and on the burner.

Here is Kprobe on about half this disc.

Again, I welcome any and all comments. :bigsmile: :bigsmile:

Got my hands on a DVD+R DL in a variety pack of Verbatims sold at Best Buy tonight. I had ripped my original Apocalypse Now Redux using DVDDevrypter and just had to give this thing a whirl.

It worked!

Now I was unsure about the auto-bitsetting in the Omnipatcher, so just to be safe I used liteon’s booktype utility, left it running just in case, and 45 minutes later I have a full 8.1 GB backup of Apocalypse Now that shows DVD-ROM. :smiley: :cool: :stuck_out_tongue: :slight_smile: :iagree: :bigsmile: :eek: :sad: :iagree: :iagree: :iagree:

This is the most exciting thing that has happened to me since getting rid of that nasty case of poison ivy two weeks ago! (true story)

I personally knew NOTHING about this whole ability until I tuned into this forum about a week + 1/2 ago.

Life is good and so is this forum.

Your PI results look ok, within the standards, but the PO results are a bit high.

Yikes. Hiking -R to 8x on the get-go? :wink:

1/ When scanning, please scan at 4x (instead of Max)… this gives us more comparable results.

2/ When scanning, make sure that “realtime chart” is not checked.

3/ LiteOn drives prefer +R. Also, in the absense of any provision to change the firmware’s write strats to compensate (speedhacking only changes the speed descriptor; doesn’t touch the write strats), +R will tend to do a better job of overspeeding than -R.
