orangejoe Posted October 20, 2016 Report Share Posted October 20, 2016 Hi, I have lots of discs with mp3s on them made by an RH1. I just got a RH910 and several of the discs won't play. I get a "cannot play" message. The track info says the mp3s are 128 kbps bit rate. What gives? Why can't I play these files? Quote Link to comment Share on other sites More sharing options...
freddyjollo Posted October 20, 2016 Report Share Posted October 20, 2016 several? so some will. what proportion? normal md converted to hiMD? any particular make. maybe the RH910 is on the way out or needs adjusting. I threw out some normal md that my Sony MZ-B10 was having trouble with, laser was clicking away having trouble with them, the were old.

Was the laser having trouble during playback or when reading the TOC? If first, I would suspect it is more on the laser's account, then on the discs'. If latter, it was probably a bad TOC. I got one discs recently been forgotten in a recorder I bought for parts, and it would not play in some of my decks, popping out with disc error. After a couple of attempts I tried pushing "All erase" while the laser was struggling with the disc. It did erase the disc, and I got a fresh TOC. This disc keeps playing problem free since then. I only have a few hundrend discs, and do not play them on a daily basis, thus my limited experience with bad discs (only the one above) is probably not representative, but my view is that md as a media is very durable. Apart from mechanical damages or dirt, it should be normally error free. Bad production media can exist though, I admit. Quote Link to comment Share on other sites More sharing options...
orangejoe Posted October 21, 2016 Author Report Share Posted October 21, 2016 It's very strange. All Sony hi-md discs. I am able to transfer the unplayable files via SonicStage and then copy them over to a different disc. Quote Link to comment Share on other sites More sharing options...
freddyjollo Posted October 21, 2016 Report Share Posted October 21, 2016 so it is only SOME of the himd discs not all? very many or just a few you didnt say. Quote Link to comment Share on other sites More sharing options...
sfbp Posted October 21, 2016 Report Share Posted October 21, 2016 The RH1 got a significant upgrade from the second generation MD players (RH10/910 and M10/100). I would not be surprised if the incompatibility is simply the result of that lack of capability in the earlier models. I would hazard a guess that the 128kbps (a lousy format TBH) is variable bit rate and that Sony hadn't learned how to do that yet in 2004. Can the 910 play regular ATRAC without problems?

orangejoe Posted October 21, 2016 Author Report Share Posted October 21, 2016 It doens't seem like there are any problems with regular ATRAC only mp3s. Quote Link to comment Share on other sites More sharing options...
sfbp Posted October 21, 2016 Report Share Posted October 21, 2016 That's a contradiction in terms. Either they're ATRAC or they're MP3. But I think I have answered it, that format is simply not playable by earlier models. Quote Link to comment Share on other sites More sharing options...
orangejoe Posted October 22, 2016 Author Report Share Posted October 22, 2016 I discovered that the mp3s from my RH1 are 48khz files which the RH1 can play. The RH910 can only play 44.1 khz mp3 files. Quote Link to comment Share on other sites More sharing options...
freddyjollo Posted October 22, 2016 Report Share Posted October 22, 2016 ah thats worth knowing. I wonder if this is the same reason I wasnt able to upload some mp3s to my NH600 himd - they would have been from the BBC using radio downloader when it still worked? hmm just had a look all are 44.1 but they have some very strange bit rates -- eg 138,129,137,132 kbs!!! I looked at the info in Sonic Stage I assume is accurate? but vlc say the codec is 160?? Quote Link to comment Share on other sites More sharing options...
sfbp Posted October 22, 2016 Report Share Posted October 22, 2016 Sounds like variable bit rate to me. Quote Link to comment Share on other sites More sharing options...
