The sample file plays fine here, and there's no crash when viewing File Info
(see screenshot attachment)
At a guess, the problem is being caused by one or more of the following 3rd-party plugins:
Nosefart NSF player v1.5 (x86) [in_nsf.dll]
TNSe's Sound core from NESten for WinAmp [in_NSFten.dll]
ShnAmp Plugin for WinAmp, by Wayne Stielau - V2.02 03-03-2002 [in_shn.dll]
SidAmp v1.33 (x86) [in_sid.dll]
Winamp2 Video plug-in v2.6 (x86) [in_VID4WA.dll]
shutAMP v2.1 [gen_shutAMP.v21.dll]
There's an updated ShnAmp (V2.04 16-12-2006) available here:
I'd seriously consider ditching Vid4Wa plugin, since Winamp's default in_dshow can play just about any videos anyway, as long as the corresponding DirectShow Splitter/Filter is installed on your system.
As for the other four, I suggest that you disable them temporarily (eg. by moving the DLL files into some backup folder somewhere) and see if the problem goes away. If it does, then re-enable in_nsf, in_nsften, in_sid, gen_shutamp one at a time, closing and reopening Winamp inbetween until the problem recurs. This way, you'll know that whichever of the plugins you restored last was to blame, and will need updating by the author (maybe there's even already updated/fixed versions available somewhere?)
And that's assuming it wasn't one of the old ShnAmp or Vid4wa plugins to blame.
ps. Although not related to the problem at hand, I recommend that you switch to DirectSound Output (out_ds) instead of WaveOut (out_wave).
Oh, and yeah, I totally agree with you about the new Gracenote Editor thing not allowing custom genres. I hate that just as much as you, especially when it keeps sticking 'General' at the front of everything.
