Have 451S -> 832S with big problem



I have a 451S that has worked like a charm for over a year. I flashed it to a 832S with VS0E and since then the end of all my burns are unreadable. I am only using 4x DVD-R. The discs are from the same spindle as I was using before I flashed without a problem. Nero InfoTool says they are Princo but they are unlabelled. I flashed to VS0G and the same problem. I also think it takes longer to write but that could be my imagination. For example, I wrote 6 700mb video files in data format to a DVD. Playing the first 5 are fine. When I open the last one in WMP it freezes and the drive just keeps flashing green and all I can do to get it to stop is open the drive - even after I end task on WMP it keeps flashing. When I wrote a DVD in MPEG1 format with 10 tracks the 9th track was partially playable and the 10th track not at all. This was on a DVD player and in the DVD drive. If I have to I will revert back to 451S with authentic firmware but I’d like to know if there is anything I could do to solve this problem, or discover the cause of it. If anyone can help it would be great.


6 700mb ?? :open_mouth: on disk DL >?


i think on normal disc: 6x700mb=4200mb, that fits on a single layer disc…

after crossflashing 451s to 832s, you should reset learnt media data in the eeprom: http://codeguys.rpc1.org/utilities/EEPROM_Utility-2.0.7.rar


@ natrap
Welcome:). Princo -R are known as poor quality media. They are particularly poor near the outside of the disc, where you are having problems. Liteons generally prefer good quality +R media. You can check your burn results with Kprobe 2.4.3 BLER scans(scanned at 4x scan speed the forum standard for comparison). You can read Interpreting PI/PO error scans to find out what these graphs mean. PI/PO is now referred to as PI/PIF. Roughly, PImax<280; PIFmax<4. Attaching disc quality scans to your post of the offending discs will help us help you.

chok0 gives good advice concerning EEPROM reset memory.


I though 6 700 mb means = 6,7 gb :S not >> 6x 700mb :S


ok, but there’s a space…


It is 6x700MB. @natrap

For example, I wrote 6 700mb video files
. Notice the plural!!!

  1. Change your disc brand. IMMEDIATELY!!! (Unless you plan on making a CD Coaster Hanging Mobile!!!OH PRETTY!!!)
  2. Also as chok0 has stated, get the EEPROM utlity and do an RLM.
  3. Read up on “Changing DVD+/-R write strategies” & substitute your PRINCO for a better MID
  4. In NERO CD/DVD Speed, click “Extra”, “Scan Disc”, to see if there are any(and HOW MANY) write errors are on the disc.


Could you recommend a better media brand. I’ve still goot about 30 discs left so I’d like to be able to use them since I didn’t have the problem before flashing to 832s. In the mean time I shall run those tests and get back to you with the results. Thanks.


I ran the Scan Disc in Nero CD/DVD speed and it showed 1 error - the last 6.23% of the disc is unreadable.


Have you done a Reset Learnt Media(RLM) yet? You need to do this because the 451S stores leanrt info on burns in different locations to the 832S.
Flash to VS0G or CG5G.
