Issues with PC to PC via HDMI: Incorrect duration and loss of video
I'm experiencing two problems that I've seen reported on other forums.
There are also several reviews on NewEgg under the Colossus regarding this issue. Some of them are over a year old.
The setup is two PCs, the GPU HDMI output of one going to the HDMI input on the Colossus. I am capturing the desktop of one computer, through the Colossus. I'm recording youtube videos (sports).
I record an hour of video, or several hours, but the duration in Windows explorer says 23 seconds for about one third of the recordings. These videos only play the first 23 seconds, even though the file is many gigabytes. They don't play in Windows Media Player, only VLC. There is no way to know if the recording is going to work or not, until the recording is complete. It is frustrating to have to start all over.
The second failure mode is that the video in the recording will freeze at some point, and only audio is recorded to the file. These files are always much smaller, because they are mostly audio. They still open in Windows Media Player. You can actually see this happen during the recording process, in Windows Explorer. You refresh the list of files every few seconds, and suddenly it will go from recording 5 megabytes a second, to about 10k bytes. Thats when I know the recording has failed, and I have to start over. Usually if it fails, its within the first five minutes.
I've tried two brand new computers (literally, I went and bought a refurbished Lenovo at Microcenter to test this issue...). Dell core i3, and refurbished Lenovo core 2 duo 2.x ghz. No other software installed on the machines besides fully up to date Windows 7 and latest drivers for Colossus, and latest update of Showbiz.
It does this with MP4, TS, and M2TS at any resolution, any bit rate, Windows AERO disabled or enabled, even if I dont TOUCH the computer during the recording, or use any other programs. I tried with/without hardware acceleration. Variable or constant bitrate. I tried RCA and HDMI for audio. I have reinstalled windows on both computers. I tried Showbiz 3.5 (bundled with Colossus) and Showbiz 5.0 (new version). I have tried feeding the capture card with two aftermarket GPUs (Nvidia and Radeon), as well as the integrated Intel graphics on the Dell and Lenovo.
When the recordings work, they are perfect. I really hope this issue gets fixed because when the Colossus works correctly, the recordings are awesome. Also, my computer is not fast enough for a capture card with an on-board processing unit. Please let me know if there is anything else I can try, or if the engineers at Hauppauge have any plans to fix this.
Note: Using component instead of HDMI isn't an option for me, because there aren't any video cards available with component out.
I think some people are having this problem with WinTV 7 also. Thats what I read in those posts, and on NewEgg. I'm working with ArcSoft in the mean time (they are going to Team-View into my computer tomorrow).
