Title: MC14 and windows vista don't agree on stars rating
Post by: robydago on July 29, 2009, 10:46:56 am

While working on solving a problem I have with my nokia phone (http://yabb.jriver.com/interact/index.php?topic=52986.0 (http://yabb.jriver.com/interact/index.php?topic=52986.0)),
I discovered that MC14 (0.34) and Windows vista explorer (ultimate 64 bit sp1) don't agree on the format of 1 and 2 star ratings.


I did this as a test (red lines are the cases when MC and vista don't agree):

In MC14
- ripped a track from an audio cd to an mp3 file
- rated the mp3 file as 1 star <--- vista explorer sees the same file rated as 2 stars
- rerated the same file as 2 stars  <--- vista explorer sees the same file rated as 3 stars
- rerated the same file as 3 stars <--- vista explorer sees the same file rated as 3 stars
- rerated the same file as 4 stars <--- vista explorer sees the same file rated as 4 stars
- rerated the same file as 5 stars <--- vista explorer sees the same file rated as 5 stars


In Vista explorer
- rerated the same file as 1 star <--- MC14 sees the same file rated as 1 star
- rerated the same file as 2 stars <--- MC14 sees the same file rated as 1 stars
- rerated the same file as 3 stars <--- MC14 sees the same file rated as 3 stars
- rerated the same file as 4 stars <--- MC14 sees the same file rated as 4 stars
- rerated the same file as 5 stars <--- MC14 sees the same file rated as 5 stars


Is this a bug or what?
Note that the test was done on an mp3 just ripped in MC14.

Agreed, I see this discrepancy too (Win7)

In a coming build of Media Center 14:
Changed: Revised MP3 ID3v2 rating tag writing conversion formula to better match Windows.

We were leaving room for '0' stars as a full width item, so effectively 0-5 became 0-255.  Now we'll keep zero as zero, but make 1-5 become 1-255.  Our rounding is a little better (correct), so the conversion won't exactly match Windows.

Thanks for letting us know.

(Oh, so you *are* a developer Matt? :) )

Just wondering if this means that ratings will now sync with my Windows Mobile Pocket Player (from Conduits), which is designed to sync ratings with Windows Media Center. Any ideas?

Cheers
