I think you're right.  Playing with it a bit more, fine position adjustment still has the feel of "two steps forward and one step back".
Guess it was just wishful thinking...

PA0PBZ:
RS-232 Decode on 00.02.01.00.03

Looks like the § comes out as a * (not sure what character set that belongs to anyway) but the rest is there:

Great - thanks for that, PA0PBZ! It's nice to know that Rigol continues to listen to our feedback and iron-out bugs.

marmad:
The ASCII decode bug (now fixed) was the last one on the list I created on the first page of this thread - excluding the AntiAliasing problem. But honestly, I'm not sure what Rigol can do about that unless they ignore Agilent's (HP) patent (or find a way around it).

OTOH, the safest way to avoid aliasing is with faster sample rates - and the DS2000 can sample @ 2GSa/s down to 2ms/div - while the Agilent DSOX2000 can only sample @ 2GSa/s down to 2us/div - so it needs the anti-aliasing feature more.

marmad:
One additional change that Rigol really should make to their firmware - and it's also worth noting for users so they will be inclined to do it manually:

If the 56M option is installed, the AUTO memory depth setting should automatically switch to using the 56M sample depth when the time base is <= 1ms. That's because the waveform update rate is not substantially different between the two memory depths (56M/14M), but the sample rate is 2 - 4x faster with 56M at those time base settings - which significantly helps to reduce aliasing.
