The last couple of days I've had a play with MP3s, FTPed onto the HDR-FOX and streamed to the HD-FOX. The first thing I noticed is that, although the WebIF browser list them in the right order (whether alphabetically or by timestamp), their order in the streamed DLNA browser appears completely random (but constant). This means if you just play them they come out in the wrong order (not much good for chapters of a talking book). The next thing I found was lack of transport control. Whatever I press all that happens is "jump to next track" or "jump to previous track". The play mode seems to default to "repeat all". Pressing red cycles this through "once", "shuffle", and "repeat track". All in all rather unsatisfactory, a bit of an afterthought. OK for a bit of background music (much like the photo viewer).
