Entertainment system DVD, etc.

[sudsguzzler]

I'm a new Gulfstream owner with a 2006 Tourmaster T36. By the way, we're new to RV's period. We purchased from a dealer that pretty much hid many problems and now we're trying to piece everything together. One item I wanted to tackle alone was the entertainment system. This was a bank repo and looks like previous owner looted all the equipment. What I've got is tv's and lots of coax cables along with some other larger cables with pin type connectors. I have a dome satellite and mini dish up top along with the standard tv antenna. Any chance of getting help on what's in between? I've got the front, kitchen and bedroom tvs. I believe the systems were Sony Dvds, but does anyone have the model that's usually used? How about any other hardware? Any help would be appreciated.
Thanks!!!!
