I’ve been attempting to record our presentations at the Inland Empire .Net Users Group for a while now. epiphan graciously donated one of their VGA2USB products to help us capture the presenter’s live screen without having to install any software. It’s been really helpful.
I just upgraded to an HP dv7t 3000 core i7 laptop running Windows 7 Ultimate 64-bit. Apparently epiphan’s 64-bit driver doesn’t seem to work on Windows 7 Ultimate 64. While their bundled video recording software captures the input just fine I have not been able to capture anything other than a one second black video using Windows Media Encoder 9 64-bit, Microsoft Expression Encoder 3, Camtasia Studio 6.0.3, VirtualDub 32-bit or VirtualDub 64-bit. Ugh.
epiphan has a stable version of their 32-bit driver along with a beta version that reportedly works with Windows 7. Neither were able to correctly install on my laptop. Their 64-bit driver was able to install and recognize the device just fine but I can’t capture video with anything other than their built-in program. Unfortunately their built-in program does not capture audio. When you capture just video, most of the codecs have a variable framerate which causes the audio and video to go out of sync throughout the entire presentation. Recording them together on Windows XP using Windows Media Encoder worked like a champ.
Oh well. While their website offers little in the way of support they have usually responded to me within about 24-48 hours when I email them. Hopefully we can get this resolved before the next user group meeting.
