DLNA support works better, and has more choices of server software that works. In fact, everything I've used, with the exception of my older server i had purchased for the 570 work pretty flawlessly.
24p for DVDs is now a separate option from BD, so the issues with DVDs forced into 24p causing dropouts is gone.
Netflix has the current up to date interface.. (moot point for me)
My 570 still works and it's about 2 and a half years old now, so i still use it as a back up player.
I had originally put it up for donation to the apartment complex for the clubhouse and the public tv, but the manager couldn't come up with a way to install it and guarantee it not be stolen, and she didn't want me to donate something so valuable to just have it stolen later. so i'm holding onto it until we can figure something out. If someone has any experience with installing a blu-ray player in public and putting safeguards into place to prevent theft, i'm all ears.
In my experience with optical Drives in general, they tend to make more noise if the disc in use tends to be warped, or otherwise off balance. It is true, that different drives deal with this better, and worse then others though. Having owned a BDP-570 for over 2 years, here is what i've noticed in my particular circumstances. If the disc, is slightly off, the unit will vibrate slightly, so it's not so much the drive motor, but the sound is generated by the vibrating disc, and depending on what the unit is sitting on produces more or less sound. To a degree any DVD/BD player will suffer from this from time to time and yes more so, as the parts age. I believe one reason DVD/BD discs will exhibit more of a noticeable difference over CDs, is because they are required to be played at a higher RPM.
Also keep in mind in most 5.25" drives either computer, or drives found in stand alone players, there are two main parts that have toe working correctly, for the disc to be well balanced, first off the spindle, on the motor itself, then in most there is a top part that locks down over the disc, that keeps it in place, if that top part has gotten out of alignment, that can also cause this to happen as the disc too won't be held in place as it should and vibrate more.
Anyway Hope this helps give a better understanding of optical drives, and things to check for. If you, or someone you know is good with computer repair, and otherwise technically inclined, many of these things you can check for yourself. If the unit is out of warranty, i'm sure you'll be charged way more then it's worth.
Hope you get your issue resolved though, and maybe sony will cut you a good deal
