When any unit that has limited space.. I always use 90 degree adapters for either the HDMI cables or the RF plugs, that ensures they don't get caught. Done that with my HDTV on my 3010RE. You can get them on Ebay or Amazon.com either way it's just a measure of prevention..
also I switched the dvd player they had in the unit with a Sony BDVE580 Blu-ray player unit. It was a direct replacement, even all the speaker connections were the same (Just plug them in the back).. NOW MY Home Entertainment System Rocks.. And I can Play the Blu-ray's or DVD's Too! I did change out the Sub Woofer included with the new unit.. And You can now really enjoy the movies!!
