14) The "Play on Enter" and "Stop On Exit" options are under the Watch DVD Activity > Settings > Change Options (for website interface: Activity > Customize > Change Options).
15) Did you try all the commands in device mode? I checked the Sony DVP-CX995V dataset, and it has the "Folder" command. If it does not work properly, then teach it from your OEM remote. You can also teach any missing command(s) from the OEM remote. The learning feature is under Device > Learn IR (for website interface: Device > More Options > Learn infrared commands). To learn a New command, you type the desired command name over the "MyNewCommand" box at the bottom of the learning page.
16) Using the Activity > Customize Buttons, you can map any command from any participating device to any activity key (soft or hard). You can also map a sequence of commands to a single key. Currently the sequence limits are 5 commands per sequence, and 10 sequences per activity.
17) Use the same sequence that works with the OEM remote. Note: Unlike the activity sequence button mapping, the activity startup/exit macros don't have a limit, but the sequence is sent only once (at startup/exit) and is not mapped to a key.
