sluggish D-Control transport after upgrading to PT8.1.1

[jmattchan]

We just upgraded to 8.1.1 from 8.0.1 and our two D-Control main units are exhibiting sluggish response and flakiness when linked up over Satellite.

The behavior is erratic. Sometimes it is okay and sometimes it doesn't work well. There seems to be a lag in Pro Tools receiving commands and so we have to hit stop, wait a brief second, then hit play to continue playing. We are used to being able to hit stop-play in rapid succession to restart playback. We are also used to being to hit play while the transport is rolling to restart playback and this is not always working.

Anyone have similar experieinces? We are on firmware 8.1.0.515

Thanks in advance,
Matt
