I bought this capture card a few days ago. I like to record PC game footage, and have been using FRAPS for a long time, but it causes a huge performance hit to my PC while gaming. I read about this capture card, with plenty of good reviews and good Youtube videos.
First, my gaming PC is as follows:
8GB 2133 RAM
128gb Mushkin SSD
EVGA GTX 670 2GB
Windows 7 Ultimate 64bit
other hardware seem irrelevant
My capture PC:
AMD 1055T 6 Core CPU
8GB 1600 RAM
500GB WD 7200 rpm Hard Drive
EVGA GT 550Ti
Windows 7 Ultimate 64bit
At first, I tried to have my gaming PC also do the capturing, but that does not work for so many reasons. The initial passthrough would work as soon as the cables were plugged in, but as soon as I opened the capturing software, it would no longer not detect any input, would disable that monitor on my dual monitor setup. Sometimes it would be a solid blue screen, sometimes a red screen, sometimes a red screen with static lines on it. A few rare times it let me record about 2 seconds of video, than its stops by itself. It was a mess that never worked no matter what I tried, so I assembled a capturing PC with spare computer parts.
My gaming PC is output at HDMI from the EVGA GTX 670 as the primary monitor, and the sound does get sent through the HDMI to my 24" ASUS monitor that does have speakers on it (which has the volume down as I have a main speaker system). After I finally got this working, the capture device does not capture audio from the HDMI, even though it still sends it through the passthrough to my monitor (which I can hear if I turn the colume up). It also does not detect any audio source if I go into the Live Stream options. I had to accept that I can never be able to live stream, and have to record my audio separately with Audacity, set to record from Windows Sound Mixer listening to my speaker output. Than I have to resync the audio and video later, a huge inconvenience. If I want to record my mic input, I would also have to set a second audio recording software to record that as well, since your mic does not go through your speaker output.
Another issue I had is when my caputing PC went to sleep, it still allowed the passthrough to work as the USB was still sending power to the device. I turned off my gaming PC for the night and left the capturing PC sleep, unplugged the USB from the Roxio device, than hoping in the morning I could just plug in the USB to the device, than turn on my gaming PC and the passthrough would work again, but it didnt, met with a solid blue screen, so I woke up my caputing PC, and it said no signal when I opened the Roxio software to capture. So I unplugged everything, restarted everything, and hooked it all up again, than the Roxio software was set to Component input, never have I done that, so it changed by itself. This is not that much of a problem, more of a; 'I cant be this lazy situation'.
All in all, I seriously expect this to work as advertised, as I expected in the following setup, which is simple and not complicated:
HDMI cable from my gaming PC goes to the capture device, than an HDMI goes from the capture device to my gaming PC default monitor. Roxio device USB cable is plugged into my capturing PC. Passthrough works, open the Roxio software on my capturing PC, hit start capture and it records the video at the 1080p 15000kbps I set it to, and records the audio that IS being sent through that HDMI cable.
I am still happy that I can record my gameplay live, and do not have to go back to watch games in Black Ops, and you dont even get that option in 99% of games. I also plan to use this on my Xbox 360 when GTA5 comes out next year and hope that it at least records audio from that HDMI input.
If you need more details on my system to try and develop a patch or update in the future that would fix the HDMI audio from the GTX 670 not being detected, let me know.
The HDMI audio playback device is listed as:
