chewy's crash course

[chewy]

I am attempting to duplicate a media burn test with discovery mode and imgburn and dvdinfo, I have found an anomaly, after three scans I keep getting an invisible peak in PIF at the very edge of the disk, transfer test and scan with cdspeed do not confirm. Has anyone else ever experienced such behavior.

Personally ? No chewy - can you post a png image of the scan for us ?

3 scans all showed the high pif max, which only showed at the very end, pulled a 96 until then.

 

cdspeed same disk

transfer test smooth as glass

[LIGHTNING UK!]

Whilst doing the scans for the media forum, I often had one that registered high PIF's or some POF's when the graph didn't show anything of the sort.

 

For me though, it was normally just a case of closing DVDInfoPro down again, ejecting + reinserting the disc and then scanning again.

 

It's hard to say where the fault lies as I would expect dvdinfopro to just display the info the drive is returning - there shouldn't really be any room for error.

 

It is weird and very annoying though so hopefully one of them will fix it!

 

I didn't try going between CDSpeed and DVDInfoPro as I knew a rescan in DVDInfoPro would probably fix the issue too - and therefore it wouldn't have been a fair test.

 

If in doubt, submit it to the dvdinfopro 'mantis' bug tracking page and have a moan

thanks luk,

I might rescan, I left the disk in the drive for all three scans but did upgrade the program after the second scan

 

btw this swisstech(sky) media isn't that bad, hopefully a good sign for media from europe

4th scan after reboot same thing, but scanned in nec 3550, matches cdspeed???????? Must be my benq and/or the dvdinfo setup on my other computer???? Uninstalling dvdinfo and reinstalling

[chewy]

well my problem with dvdinfo and this machine must be related to the size of the disk

a 4400MB burn

I'm sure not going to waste any of these disks on discovery, saved for long term data archiving
