Like almost everyone else in here, I am an early adopter and often find myself with more disposable income than common sense. My first experience with a set-top DVD player that offered regular firmware updates was with the Momitsu v880. It was playing with that unit that made me understand (more accurately brought it home) that this was more like playing around with a modded home-built PC than your average piece of consumer A/V gear.
That realization brought something home to me that I believe may not be sinking in with some folks in this forum. At least with a home-built PC, you only update the bios when there is a genuine need to do so...Unless, that is, you are just begging trouble or consider the computer a test-bed and have other boxes to fall back on. I guess it all comes down to the old dictum, "If it ain't broke, don't fix it."
My v880 had the truly crappy EPO loader, so every firmware upgrade was at least a bit of light in the darkness...Any hope of making the loader work better was a glimmer of hope if you didn't want to retrofit it with a Lite-On loader.
The OPPO, thank you Jesus!, is not the v880. If the machine is doing what you need and you don't have the lip-sync issue...as I do not...then you do not have to slap on every firmware update that is released. I guess the bottom-line is that if the newest release does not address some specific problem you are having, then don't use it and let well enough alone...Unless, like me you just enjoy experimenting with your player.
I have tested the 0220, the 0228, and the 0302...All managed to break more features than they fixed, so I have reverted to the 1022-D and will stay there until the next release. I suppose the bottom-line here is that if you enjoy doing the updates to see what happens, go for it. If however, your OPPO is performing acceptably, you do not have to use every release that comes down the pike.
