Hi Thanks for your fast responses and sorry for my late reply. I have now tried the RegEdit fix for Matshita CD/DVD (Removing upperfilter and lowerfilter) as described on several places (example: http://support.microsoft.com/?scid=kb%3Ben...p;x=12&y=13 ) Tried to burm a CD from an IMAGE but Vista frooze again, this time after 1:21. On the screens I have: Time elapsed: 1:21 Complete: 27% Buffer: 100% Device buffer: 100% In the bottom where info is displayed it says: Writing sectors In the log window the last lines are: Writing LeadIn... Writing session 1 of 1... (1 Track, LBA: 0-322876) Writing Track 1 of 1... (MODE1/2048, LBA: 0-322876) The same time Vista frooze I tried to Resize the log window and had just clicked the lower right corner to resize but I think this is just a coincidence (but you never know...). No other applications were running. Could this be some software conflict? For example Antivirus (I use Trend-Micro Officescan) or maybe some other software wanting to access the CD-drive when it is in use by IMGBURN?

Thanks for fast answer, I will check storage drivers as you suggest. I have not installed any apps that could interfere.

I run Windows Vista Business on an SONY Vaio laptop with built in DVD/CD reader/writer. I recently installed Imgburn 2.4.2.0. First I used it to burn a dual layer DVD, it worked great without problems! :-) Now, one week later I got problems, burning freezes Windows Vista. I tried to burn a Dual Layer DVD and suddenly after approx 30-70% Vista Frooze. Only on/off button could reboot my laptop. I have now tried to burn CD and now it freezes Vista almost directly when it starts to burn. The following happens: I start IMGBurn, no problem. CD/DVD drive is detected, no problem. I choose the ISO file to burn, no problem. I insert a blank CD, imgburn detects it, no problem. I start to burn and IMG starts to "filling buffer". When buffer is 98% I hear the CD/DVD drive spin up and now Vista freezes! Probably this is something in my hardware or Windows vista but I have not done anything lately with my laptop. Anyone that have a clue what it could be or if I could try some other settings? Should I try to reset DMA but the imgburn FAQ stated this for XP, not Vista? Below is a sample from the latest log (unfortunatly imgburn seems to chas the log in memory and dont write it to disk so I never get everything in the log...). Debug is enabled so the log is long...
