MP3 Pro files are basically normal MP3s with an extra data stream for high frequencies IIRC. Any MP3 player, including the TH55, can decode the MP3 part of the file, but NOT the extra high-frequency data - this will just be ignored by the MP3 player. So basically yes you can play MP3 Pro's but they'll sound crapper because of all the high freqs missing

I would love to be able to play them on my TH55 when I get it since I could then basically use my old 128Mb MS(s) as 256Mb MS(s)... __________________ Regards, PC

Due to some strange limitation in the T665's DSP chip, it can only play back 44.1kHz MP3s, but they can be any bit-rate from 32k upwards and can be stereo/mono and CBR/VBR. The most common reason for MP3s not working on a T665 is that the sample-rate is wrong. See if you can get it to work because I'm 99% sure the TH55 uses a similar DSP to the T665, so if the MP3 doesn't work on your T665 it probably won't work on the TH55 either

Got the following message on the Clie: *This track is unavailable for one of the following reasons: The Memory Stick media is write-protected or does not support copyright control, or the track file is corrupted.* Personally I believe that the Clie just can't read MP3 Pro files unless someone can prove me wrong (which I would really appreciate)... __________________ Regards, PC

Maybe the T665's DSP is getting hung up on that? Alas the only 2 filetypes I use are OGG and MP3 - I don't have anything that can make MP3 Pro files so I can't test it...

It doesn't say in the TH55 manual, but I'm hoping that your speculation is true... that the Th55 will play Variable Bit Rate MP3s... unlike the TG50 which only plays CBR.

From what I'm seeing, the TH55 (at least with the default player) does not handle VBR MP3s. I just upgraded from the N760C, which had no problems with VBR MP3s.

Should I expect better luck with a different player?

(follow-on): I'm working with 44.1kHz MP3s. They're showing up as OKbps in the Audio Player.

Got the following message on the Clie:

This track is unavailable for one of the following reasons: The Memory Stick media is write-protected or does not support copyright control, or the track file is corrupted.

It's the same message that you get trying to copy DRM files to a non-magicgate memory stick, or a memory stick Pro.

What kind of memory stick are you using?
