i think you're missing the point i am making... if i change an option in SBS, like the ones you or Jim mentioned, SBS should NOT need to rescan the files, new or full; it should simply rebuild the SBS tables from the tag cache table (phase 1) or better yet it should just make ALL the tables it could ever need regardless of the toggle type options, and then just switch to those tables when the option is changed. in what i am proposing, phase one just makes the raw tag cache table, and that should be updated whenever the OS detects file changes. at that point, phase two should kick in and make all the tables SBS would ever need, in the background, and the options would just control final display of data to the user, and have nothing to do with needing a rescan, (in most cases). i can not understate how much i HATE IT when SBS kicks off some "automatic rescan" or requests one. it shouldn't ever be necessary UNLESS data changed, but not when [most] options change. erland;578431 Wrote: > I suspect most(all?) of the current options that requires a rescan works > this way.

TPE2 is a perfect example. b/c of the dumb "one master list" display SBS uses, i have to decide between using albumartist tags for my master sbs list, or artist tags, and stick with it, unless i masochistically want to full clear and rescan everytime i want to flip between them. dumb! if both tables for the TPE2 option were made during the second phase of a scan, i could just switch between them by toggling the option. (although i want to stress that this issue is equally a UI downfall, not just a scanning one) in other words, winamp lets me browse and sort between AA and artist via a click, and i can even display them together. all thats a fat NO CAN DO on SBS, without screwing with the TPE2 option, and a full rescan, YUK! 3. the scanner right now is, imo, opaque at best. if you had a raw tag table for phase one, you could figure out pretty quick where a problem was, be it in how a tag is read, OR in the phase2 logic. 4. all this stuff could happen in the background. i agree with Greg and i thought you... -- MrSinatra www.lion-radio.org using: sb2 & sbc (my home) / sbrec & ipeng (parent's home) - sbs 7.5.2b - win xp pro sp3 ie8 - p4(ht) 3.2ghz, 2gig ram - 1tb wd usb2 raid1 - d-link dir-655 - 43k+ mp3 ------------------------------------------------------------------------ MrSinatra's Profile: http://forums.slimdevices.com/member.php?userid=2336 View this thread: http://forums.slimdevices.com/showthread.php?t=82096 _______________________________________________ beta mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/beta
