Okay I kinda need help of how to translate all this complicated stuff. I'm using Nero CD-DVD Speed to check out the quality of my DVDs. But I don't know what it all means. Can someone please help me? I just want to know what PI Errors, PI Faiures, Jitters, Meaning of Graph (a), etc. I've posted a sample for some purpose... http://img146.imageshack.us/img146/3010/nero2wc2.png http://img148.imageshack.us/img148/7048/liteondvdrwshm165p6sms0yq9.png Any help appreciated. If this is also in the wrong area, moderators please feel free to move it in the correct thread.
Hi there, I can't find a good site that really explains what a PiPo Scan is. But let me try to show you what I know about the graph. 1) I have a NEC-3550a drive, and the Author of CDSpeed mentioned not to read at MAX speed, I should read at 4x (5x in my case) 2) The Graph on top, if I recall should never be above 400 3) The graph on the bottom, should never be above 8 or 10 As you can see, your media is 0% quality. Those Ritek should not be burned more than 2x or 4x MAX. What a PiPo Scan like this, I would expect issues on playback. Skipping, Freezing etc... Now all I know about the graph is this. The above graph shows you errors. You are aloud a certain amount of errors before it's serious. After a certain amount errors in a row, it will generate an error on the bottom graph. This is why it's normal to have a few errors on the top graph but not too many on the bottom. I know this helped, at least a little. If I ever get a good document on how to read a PiPo Scan and a good explaination, I will post here !
