I was happily burning with Nero using 80min CDRs (intenso) but I came across couple of big AVIs so I decided using 99min CDRs (infiniti) All was fine, over-burnt the CDs no problem. Gone back to 80min Cds for normal burning of 690mb files and started getting coasters, tried simulation and every time I got seeking end of track error at 97% . Friend of mine has exact same model of burner (Plextor 241040A) so I borrowed it, straigh swap and exactly same error. tried uninstalling and reinstalling Nero, that didn't help. Any other suggestions? Please don't say try other software as I like Nero too much to give up on it. TIA.
