I sold an Onkyo TX-601 receiver to a friend a couple of years ago and this weekend he got a new set of speakers, so we took the opportunity to also rewire the setup with better cables. This receiver has one caveat: the 6.1 channel input pyggy-backs on the DVD a/v input - essentially, the designers assumed that any SACD/DVD-A player would also be the DVD-V player. To keep things simple I thought why not just use the analog 6.1 inputs for all DVD-V content as well - which is the way we left it Sunday night, although I can easily come back and reconfigure.

Is this configuration compatible with 6.1 DTS & DD? If so, then I presume that any conversion is then handled inside the player, right?

A couple of side notes: we had to adjust the volume up a bit (compared with using the coax digital input). The sub volume also needed to be turned up, but it seemed a bit crisper and punchier than with coax digital.
