I think I am going to buy a hdmi cable and hook it up from the dvd player with surround to the blu-ray and it should work.
Don't that will not work. The HDMI socket is an output for TV connection.
Your unit has NO HDMI inputs, but up converts to an HDMI output.
Your unit is a very nasty HTIB indeed.
The only way you can connect a Blue Ray player is to connect the HDMI output or component output of your of your Blue Ray player to your TV. Your Philips unit has no high quality TV inputs.
To get sound you must connect an optical output or RCA digital output from your Blue Ray player to the optical or RCA digital input of the Philips unit.
You must select the input you use in the set up menu.
Now you will only get Dolby Digital 5.1. Your unit has no DTS codecs. Most Blue Rays are DTS encoded and not Dolby now. The reason is that DTS and DTS master encode can run in the same stream with DTS 5.1 as the core.
Dolby Digital 5.1 and Dolby True HD have to have separate tracks. So studios are moving away from Dolby Digital/Dolby True HD in favor of DTS master HD which has backward compatibility with DTS 5.1.
So you can not play Blue Rays that are not Dolby encoded.
You player does not support Dolby True HD only Dolby plx and Dolby Digital 5.1.
This unit is really pretty useless and belongs at the recycling center.
If you want surround sound you need to avoid HTIBs.
You need a decent 5,1 or 7.1 receiver and decent speakers, not these nasty puny satellites and a sub that isn't with a 6.5 inch woofer.
Sorry but that unit of yours is a waste of space and above all the world's precious resources. It should never have seen the light of day. I think that is about the nastiest unit I have run into on these forums.
