In all builds of Windows 10 Technical Preview up to (and including) 10056, every time when I launch ArcSoft TotalMedia Theatre 188.8.131.52 (this is a multimedia player capable of playing Blu-Ray video discs) (184.108.40.206 is the latest version), a BSOD (Blue Screen of Death) happens.
Mb: ASUS P8Z77-V Pro (Intel Z77 chipset)
CPU: Intel Core i5-3570K (socket LGA1155)
RAM: 8 Gb
Graphics Card: (Gigabyte) NVIDIA GeForce GTX 670 2Gb
When I launch the same TotalMedia Theatre on the same PC in Windows 7 or Windows 8.1, it works fine, without any BSODs (never had even one in this program on pre-10 versions of Windows), and plays my Blu-Rays perfectly.
The problem is that ArcSoft had discontinued the development and support of their multimedia player in 2014, so this is the latest and last and final version and they won't make further patches anymore.
I don't know if the BSOD is caused by a bug in Windows 10 or a bug in TotalMedia Theatre, or some bugs in both products.
