I am a developer myself, so I know that I am running a pre-release and even pre-beta software which may contain lots of bugs. But as a User of such a software I see it as my Job to report bugs that I find in there, in order to help the devs fixing it.
If the issue is something more complex, I would have agreed with you but since this is "just playing a 1080i vid and see what happens" I am definitely not going to install the software again, test it, and then install my normal system again and set it up again. If the devs don't care about their work enough to investigate such an easy to reproduce issue, then I am defintely not caring about it either.
I know that this is free software, and with my report I wanted to help the devs, but if they simply don't care about it then this error will make it into the production builds. And as Production builds are release less often then Alpha, lots of users who expect a perfect software will find the bug and consider it unusable, and not just for a day or a month but most likely for ever. So if you really want to damage the reputation of your project, you are welcome to do so. I am not expecting anything so I have removed it and will move on now, you know about the bug and can investigate it or have it go straight into production, thats up to you.
