When I play movies with ATMOS track (and I've only got one - Roger Waters The Wall) I get drop outs in the audio. Same happens when I play the disc in the BDP-93.
Actually wmcclaim provided a solution before me: I just rephrased it, so thanks should go to him.
IIRC, the Oppo 93 can experience dropouts on bitstreamed lossless audio codecs if the title has complex seamless branching: this is fixed by outputting multichannel PCM from the Oppo instead of bitstream. Unfortunately, outputting PCM strips the metadata that Atmos uses, so it isn't a solution for titles where you want Atmos audio.
I believe the Oppo 103/5 doesn't have the issue and I would suspect the Oppo 203/5 also has the issue fixed.
The problem with daisychaining an Oppo 93 and an Oppo 203 is that the problem is with the Oppo 93 and will be propagated into the 203.
If you have an Atmos title in official disc format, I would suggest playing it on the Oppo 203 directly. All bets are off for playing files from USB drives via the Oppo 93.
A cynic might suggest that the Atmos issues play into the hands of the studios who have ensured great difficulty in playing what they see as copyright infringing files on later, more compatible players, leaving only the earlier players such as the 93 which coincidentally have issues with certain titles and thus playback problems: a catch-22 situation for the consumer wanting flexibility.
However, since the Atmos issue is related to complex seamless branching, a workaround would be to obtain a file that had seamless branching removed whilst still keeping the Atmos metadata: the Oppo 93 should have no problem with bitstreaming such a file (were it obtainable).
