Yes, none of those memory depths are available with both channels turned on - except indirectly via AUTO at certain timebase settings - so they work fine.
--- Quote ---Or does turning on the 2nd channel cause all hell to break loose? which was the point of the bug report...

Yes, both channels turned on invokes the bug listed above.

@MikeR: I think you're being a little optimistic with those transfer speeds you mentioned; the bottleneck isn't really the interface - it's the Rigol.
When you send the command :WAV:BEG - the Rigol starts filling a buffer in the DSO (~2MB large). If you ask for the data before the buffer is filled, you'll get it - and the DSO will continue filling the buffer (if necessary). If you don't empty it before it's filled, the DSO will wait.
But it's possible to time exactly how long it takes the scope to fill the buffer. In the case of 1.4MB, it's ~5.95s (if I remember correctly, it takes ~8.6s to fill it entirely). This is not taking transfer speeds into account - this is purely the time it takes for the DSO to move 1.4MB of sample memory to the output buffer. Rigol have clearly written the firmware so that external events like reading memory won't have any impact on the DSO's real time performance.
In terms of transfer speeds over USB, it takes my computer about 1.275s to move 1.4MB from the Rigol.

Thanks, Evi! Are you using USB or LAN connection?
