- can't reach all the menu items on menu screens of DVD ISO files e.g. special features
To access the full manu navigater needs full DVD licensing, we'll try but it's complicated.

- would like to have an option to return to the file menu when playback of a file is complete, rather than autoplaying the next file
Great idea, let us work on it.
- would like to have the option to show more files on the browser screen instead of the preview window, which I don't use. (thumbnail preview, I would use though)
hum... it's not as easy as it seems to be now, but let us check again.
- subtitle menu - I can't access any of the buttons to change the subtitle parameters - can only turn on and off (v. 111 firmware)
The new subtitle control manu provides a lot of ways to control the subtitle, it was in 1.13 but please wait for new FW.
- would like to have an option when I start the O!Play to jump immediately to the last network folder I was browsing when I turned it off, rather than having to navigate through all the screens.
Good idea, kindly let me check.
- volume of the O!Play seems quiet - I use it at max volume all the time.
Urr... it's line out only, so maybe need your help to turn up the TV volume as well
- O!Play often turns itself back on after I've powered it down.
@@, not sure why, was it taking other remote controller's signal?
- would like slow motion playback options
Seems to be HW limitation at this moment, but let me check
- like others would love jump to time, jump forward backward 1 minute / 5 minutes
Will be added
- the whole network sharing system is inadequate and needs to be addressed, but I think you are well aware of these issues
Yes, -_- please bear with us
- would like to be able to access shared HD storage on the O!Play through the network (use O!Play as a NAS).
But we do have SAMBA now, it should work
- finally, the name of the device... O!Play.... is stupid. But its too late to change that.

Next time drop the exclamation point.
Haha.. thanks for the feedback, O!Play meant to be "All Play, all format, all family, everywhere..."
