As Justin said you are good to go with the 6.1 inputs.
Quite a climate change from Roswell to N.C., and a lot fewer aliens too
When you get the new player, you may want to hook up the digital connection, in addition to the 6.1 analogs. That way, you can still use the Yammy for DD,DTS,and PCM, and take advantage of all the ambience processing modes that Yammy is famous for.
The player will handle DVD-A and SACD and send it along in analog.
A word of caution. Do a search here for Bass Management. Most of the currently available universal players do not do BM properly, which can mean that bass is not sent where it needs to be. I suspect that your Yammy, like most receivers or pre/pro's does not apply BM to the 6CH inputs.
Some of the newer players (not yet out such as a new one from Denon, and a Pioneer) may do it right. No one will know until they get one and test it. I have a Pioneer 45a, which gets it wrong in several ways (search 45A if you want the whole story).
The point, if I have one, is if you buy a player today, you may want to budget for an Outlaw ICBM ($250 + cables). It will go between your player and Yammy, and it does BM 100% right. Thats what I did, and a lot of other universal owners are doing as well.
Good Luck,
