The issue is with regards to the Optoma HD300x projector When ever im watching a movie, say on 1080p on "cinema" image mode,the video quality seems a bit jerky for my liking. I'm wondering whether this is a HDMi issue as the cable is well over 2 years old and is approximately 3 metres long. What may the issue be? is it the HDMI output or is it something wrong with the projector? P.S. the 1080p video output is via an Acer, high spec laptop.

it sounds like the A/V reciever does not upconvert the component signal to HDMI. Not many do. The Marantz recievers will (SR6001, SR8001, etc..). Also bear in mind that HDMI cables are finicky and may require amplification over a few meters long.

My understanding when we purchased our IN72 2 years ago is that there wasn't any additional benefit for Cable box using HDMI since the IN72 does not transmit audio so using component cables for cable was optimized enough. We have our DVD player connected via the HDMI only. Possibly the transmission from cable box through an HDMI is not compatible audio is confusing it? hard to say. Cable HD channels look awesome thru the compenent cables, the max for IN72 is 480i anyway.

We've got 35 ft cables for all 3 hdmi, compenent, and that vcr one too and it's worked great.

In the settings menu, go to video settings. You can have the PS3 search for "optimal settings" This will tackle both video & audio.
On a side note, you didn't need to spend all that money a HDMI cable. ( I'll bet it's a 'Monster' cable, right? ) The $16 Phillips at walmart is just as good. Unless your doing "broadcast quality digital" work, the expensive cables are overkill. Sorry, bro.
