I ran a scan at 2.4x ECC8 this time, and the scan came out within specs. Scanning at 4x gives high PI/PO I don’t know why.
The point being a DVD Video is played at 1x, so it’s pointless to worry about high PIPO errors in KPROBE when scanned at 4x, since your DVD Player will NOT read the disc at 4x. Of course you can scan at a high rate to compare good and bad media, but my whole point is, if you use GOOD quality MEDIA, you shouldn’t worry about your LiteoN reporting high PIPO when KPROBED at 4x,
I’ve burnt a Memorex 4x, at 8x on my 811S, and when KPROBED it it started well then a HUGE skyrocketing of PIPO and high PIPO throughout the whole disk I never seen so high of a PO which was in the thousands Strangely enough the disc played from start to finish on my DVD Player WHY ? Because the DVD Player reads it at 1x I think this is a case of a GOOD media combined with crappy reading from my liteon So far I’ve done about a dozen movie DVDs, some at 4x some at 8x, and all have worked fine from the start of the movie to the end of it without problems… Same for all data and backup DVDs.
I took those discs reported with extremely high PIPO and played them on different DVD-ROMs and running a binary compare bit for bit with the original data on my HDD and ALL discs came out 100% identical.
AND to top it off, I applied CD Stomper labels to ALL of my DVDs and all worked perfectly. Interesting to note, that I ran all my probes before and after labelling and there were no changes in readings.
Another strange thing, I did notice when burning my Maxell or Memorex 4x, at 8x on my 811 that it would start burning at slow speed, get higher at some point, then finally switch to 8x, during switch periods the light would be orange briefly… I can see this transition in KPROBE scans, however when looking at the burnt DVD, it is nice and clean, no circles, marks or other anomalies reported by some peeps here, and no changes in colour, just perfectly even.
I’m still puzzled however as to the fact I can take my same media and burn it on another DVD burner, and scan the SAME media on my 811S in kprobe and get perfect results at 4x ECC8 scan, disc being still playable. This would rule out the bad reading theory.
I’m really puzzled by this.
