Yamaha Receiver + PS3 slim bitstream Question

[BornToBeBlu]

Hi All,

So a few months back I bought a nice Yamaha RX-V665 Receiver and have been very pleased so far. A little while after I got my receiver I got a PS3 slim so I could bitstream audio to my receiver. However, lately on the display on the receiver it will keep switching between the lossless audio format and the lossy audio format. I was watching Monsters Inc two nights ago and it keeps going in between DTS MSTR HD and DTS-EX Matrix or whichever the lossy one below it was. I know the PS3 warns me that some audio might not be available bistreaming but I was wondering is this normal? There is no change in audio quality that I can tell when it's switching back and forth, so I guess it's just a preference thing that I'd like the display my lossless audio all the time. Has anyone else experienced this? I've also done a hard reset on the ps3 and set the audio back up and it fixed for a little while but it came back. I've also even tried unchecking all the lossly formats when setting up the ps3 audio and it still didn't help. Any suggestions?
