I am encountering problem concering media playback that is persisting throughout Virtualbox 4.1.x till
4.2 betas. Thus, my main question is to solicit feedback from users of similar setups whether
my tests work for them. It's hard to believe that no one has encountered this, but googling
has brought no enlightenment so far: My experiences are practically identical on two
machines, hardwarewise similar (2500K sandybridge CPU, 8GB Ram), with the exception
of graphics, a dedicated NVIDIA card on one machine, onchip intel graphics on the other.
proprietary nvidia drivers in use for the nvidia board. One machine has been
continously updated for a about a year (linux and windows guest installed then),
the other machine (with 4.2 beta was just installed two days ago, fresh barebones
windows install)
Host: 64 bit Linux (debian wheezy)
Guest: 64 bit Windows 7 ultimate
Appropriate guest additions installed, tried with and without WDDM 3D driver
The windows guest has two cores + 4GB RAM allotted, 2d/3d accel
turned on, 256k Video memory allotted!
Problem: media(video) playback on windows guest fails, e.g., I cannot
reliably watch an *avi file, or play a DVD movie (physical DVD in DVD-ROM
drive, passed through to guest). The DVD plays fine on Linux!
I tried windows media player, MPC-HC and VLC and various combinations
with 3D guest drivers installed or not installed. Some parts occasionally
works, but *no* combination passes consistently both my test cases (*avi
file + DVD) Note
Note: I couldn't care less about watching DVDs on the windows host, *but*
literally nothing on the windows side involving graphics works reliably
(resizing a jpeg photo occasionally crashes the
whole VM), and this is starting to interfer in earnest with my workflow.
I am happy to provide details, but, again, I'd mostly like to solicit feedback
whether anyone else has this working!! I consider myself proficient on
the Linux side, but I am a neophyte on Windows; so I'd definitely appreciate
also hints/suggestions what to check concerning windows settings.
Looking at the virtualbox logs, I see nothing out of the ordinary.
Given that I use two different 3D stacks on the host side (proprietary
nvidia driver, as well as open source intel), with identical symptoms,
makes me suspect virtualbox/windows-guest, or severe user
error ...
Thanks in advance
