using hdmi splitters with capture card

[TLE6]

so I ordered a PCI-E capture card (Avertv HD DVR High Definition / Analog Video Capture Card PCIe MTVHDDVRR) and I'll need an hdmi splitter so I can play on Xbox 360 and capture at the same time (Play on TV - have it capture and record on PC)
Other users with this capture card say they use an hdmi splitter to do this and it works fine, however I'm reading mixed reviews on splitters, some people say you need a powered one (plugs into wall outlet) others say a simple cheap splitter will work fine.

can anyone head me in the right direction with this?

I would just get a powered HDMI splitter and not even try a passive one. I use a powered one to split the HDMI signal between my video projector and my HDMI/VGA LCD monitor and it has been working perfectly for a couple of years. They aren't that expensive. The passive ones sometimes work, but often times don't.
