I have a similar problem.
I just bought Easy VHS to DVD 3 Plus (box kit HW and Sw) and a new Samsung burner (TSSTcoprCDDVDW SH-224BB SB00- checked and it is latest firmware) from Newegg.
1. Installed both on Dell Vostro 200 Win XP SP3. First Project. No problem. Converted VHS Video to .mpg and burned no problem.
2. 2nd project Converted to .mpg started the burn and went to bed. Next morning woke up to blue screen of death. Rebooted. Tried burning 2nd project get "Problem Writing to Disc Error".
3.Did a repair Easy VHS to DVD 3 Plus software re-installation. Tried burning 2nd project get "Problem Writing to Disc Error".
4.Next unistalled and reinstalled Easy VHS to DVD 3 Plus as described in000012552- Preparing your computer for installing Roxio products.
5.Tried burning 1st project again to disc but get "Problem Writing to Disc Error". Note this worked the first time.
6.Next burned first project using Roxio Creator 2009 on same disc, compure and burner that failed using Easy VHS to DVD 3 Plus and it burned fine and played in home entertainment DVD player.
What needs to be done to get Easy VHS to DVD 3 Plus to burn discs reliably?
