#1 problem is you switched cards. All bets are off after that.
#2 problem is using long cables is always a recipe for disaster - if you look in the AV subforum, anyone that has HT Projectors mounted on the ceiling with long cable runs that mysteriously has problems all of a sudden crop up, first suggestion is to try a direct short cable - and a lot of times it fixes it. Long cable runs means signal quality issues.
#3 problem is you're using a passthrough via your receiver. Again, you switched cards, so there's absolutely no telling how/whether your setup will play nice with the passthrough.
On paper, it should all work. In practice, you have three things that historically cause headaches for AV setups. Take and test each thing one piece at a time.
