I have installed and tried various mediashare software with various success, including WMP11, Tversity, Twonky, ORB and Nero mediahome 4 to my hr 21's. Just trying to find that one program that I can use consistently for photos, video and music. Seems like one with take care of one type of media, that the other won't on the hr21's. I know there is a ton on info on codecs and transcoding, etc, but the more I read, the more I confuse myself, so I am not sure why I get some of these inconsistencies with the various programs.. WMP11 - will play my mp3's and photos (jpgs), but get an X by the mpg videos. Also, will not play wma, drm free music. All of these I can play on my computer using WMP11. Tversity - works the best on all media formats above, but will not stream AVCHD from my camcorder, however, Twonky will on my ps3. I also downloaded the codecs and the most recent version of Tversity. twonky - will not play mpg videos on the hr21 that Tversity will play. Will stream music and photos. However, twonky will stream avchd video on the ps3 flawlessly, with FF, RW, etc. Nero Mediahome 4 - the most recent version. Can't get that to recognize any media format, all have X's by them - photos, music and video. Also, does not recongize the files in my "folders", can only see them if I select "all", etc. on the menu. Orb - I like the folder structure of orb the best, but video is extremely slow and choppy, can't play mp3 music files, all have an X by them, photos work. I have not dowloaded any other codecs other than what I downloaded with Tversity. I am still trying to figure out all the codec technology, what it means and how it applies to the transcoding. Codecs are needed to transcode the media type if needed for the HR21 to play it, correct? Part of my problem is my lack of understanding of which codec to use, how to use them, when to transcode, etc. Not sure if I want a full understanding, but enough to try to get that "one size fits all mediashare" for both the HR21 and my ps3. I don't have a ps3 at every TV, and like how you can play music and photos at the same time on the HR21's. The PS3 seems however to do a much better job with the various media servers and is more consistent, and solid. I also probably have so many codecs loaded from the various programs, I am probably messing something up. I try to experiment with one server loaded at a time. I know there is ton of great info and most rehashed a lot, but still somewhat confused or frustrated why there isn't one program that will do it all, and do it right on the HR's. It seems that everybody's situation is different - some can play one format, while others can't, etc. Specifically looking for any advice on what I might need to do to get the X's off my music files in ORB as that program looks promising, and why I get the X's on my video files in WMP11, when the other programs seem to work. Do I need to "deactivate" any codecs that might be running on the computer? Media share is an awesome feature, just wish it was more plug and play. Thanks for any advice..
