I would read them, if you haven't already. It is highly dependent on the media you are consuming, so it's really something you would have to answer for yourself. It's usable on GXL devices with 1080p media, but the release notes outline quite a number of things that are not working that are important to some people. I mostly use it for MPEG2-playback of 480/720/1080 progressive/interlaced content (PVR recordings), and MPEG2 HW decode is totally broken so it is all ffmpeg software decode currently, beyond that I have used it to playback Xvid and H.264 content which seems fine.
Thank you frakkin64 I appreciate your response. Yeah, I did read the release notes. There's a few things in there which make it a bit of a deal-breaker. Sometimes it's better to stick with what you have, even if it's slightly dated, but at least reliable.
Thank you for the guidance, those who kindly responded.
