I was able to download and install Rio 300 plug-in within MM 8.0.315 quite smoothly and Rio Icon appeared promptly under CD, DVD, & Handhelds.
However Rio 300 plug-in does not function properly :
(a) Clicking on Rio Icon invariably shows message " The RioPort device is disconnected or powered off. Please reconnect the player" - this is despite the fact the player is switched on and properly connected to Parallel port.
(b) After unplugging/re-plugging the connecting cable into the player - a +sign appears next to Rio Icon and an Internal Icon appears below. Icon for External does not however appear.
(b) Clicking on Internal does not show any contents and many a times MM8 stops responding/freezes.
