I never liked WMP, but it seems everytime MS upgrades it, it's performance gets worse. The only thing I used it for is watching DVDs on my computer and listening to music sound clips on Amazon, etc. It won't do either now.
When I try and watch a DVD it gives me "WMP has encountered a problem and needs to close". If I try and listen to a music sample on Amazon, it brings up the small player, but won't play anything, it just says "done".
I’m not a big Apple fan but respect them.
Apples iTunes is maybe the best WindowsXP player available and QT that is bundles with it and is its core players most video formats as well.
I’m a charter member of Music Match and get life-time upgrades. I like it too but its got its issues and isnt’ really a video players.
For Video (mostly DVD) I love WinDVD, currently using version 5.
I change my iTunes options as follows; Edit > Preferences > Advanced tab, then Importing tab.
I change the ‘Importing Using’ type to MP3, then change setting s to Custom, then choose Stereo Bit Rate 256k, Use Variable Bit Rate, Quality to Highest for a very good sounding MP3. I also, use this to RIP WAV’s for lossless tracks.
