Here's the problem I just realized...this card doesn't really work without it's proprietary software (RECentral) that comes with it. I was expecting to install the card and drivers, and be able to use it with any third-party software. But none of the third party softwares I've tried can detect or access the camera.-superboyac
Normally, you select the card for the source and then somewhere in the cards preferences you select which input on the card to use, (HDMI1, etc). The camera per se, shouldn't be detected by the computer at all - you'll either get a picture on screen or you won't.
At least this has been my experience with analog/DVB-T capture using internal/external sources.
Looking into it some more, other more professional cards recommend being able to write at 500 MB/s, which probably requires a computer set up with RAID hard drives or SSDs (which I don't have).
The card you have has onboard hardware MPEG4-AVC encoding so if it's enabled it shouldn't need anywhere near 500MB/s - 1080p50/60 data rate is ~3Gbps for uncompressed RGB.
Data rate for streaming 1080p MPEG4-AVC is ~22Mbps which is why you can watch your standard BluRay movie over a decent WiFi connection - so if hardware encoding is enabled your system should have no trouble coping with that, (provided there isn't some other process doing weird things - I close down all other non-essential tasks when doing analog capture).
Do I just need to record at lower resolutions/framerates?
DO I need a different card with general drivers and not proprietary software?
Do I need to setup a RAID system?
If you want to give Microsoft a try, you can download
Microsoft Expression Encoder Free which will allow you to capture from a video source. If you want to stream live then you need to buy Expression Pro.
Anyway, something to try to start with.
