Guest type: Windows Host type: Linux

Description

Host is Ubuntu 12.04 64-bit. Guest is Windows 7 64-bit. Ubuntu package virtualbox-qt-4.1.12-dsfg-2

Silverlight video playback (e.g. Netflix) works correctly for 1-10 minutes before stopping, leaving only a black screen in the silverlight window.

Workaround: Run with only 1 CPU allocated to the guest OS.

Hardware:

Hardware- Core i7, Nvidia gt430 based gpu. Virtualbox config: 5000MB RAM allocated to guest, dynamically allocated disk (VDI). VT-x/AMD-V enabled, nesting paging enabled. Tried with 3D/2D acceleration disabled and enabled. All other settings are installation default.

I forgot to mention that Guest Additions are installed.

Thanks to this information I was finally able to watch live TV inside VirtualBox on Ubuntu 12.04/x64. I had the video lockup almost immediately, until I noticed I had 2 CPUs allocated to VirtualBox. Set it to one and the problem was solved.

Thank you!

For the record, my system specs are the following: {{{cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=12.04 DISTRIB_CODENAME=precise DISTRIB_DESCRIPTION="Ubuntu 12.04.2 LTS"}}}

{{{uname -a Linux mylaptop 3.2.0-40-generic #64-Ubuntu SMP Mon Mar 25 21:22:10 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux}}}

CPU: Phemon II X4 1.8GHz RAM: 6GB

Virtual machine: 2048MB RAM, 32-bit Windows XP

Thanks for the info! I was running into this problem as well. Quite frustrating. Reverting back to 1 vcpu fixed it.
