WMV file limitations

Another question was around WMV (and other video codec) limitations. Rest assured, there will be some...no 1080p video on your Zune for you!

One additional point - the Zune software will know the limitations of the device, and if you try sync incompatible video, it will automatically transcode it to a friendly format. Transoding can be slow, but at least it'll get onto the device. The limitation here is that the video must be a format the Zune software understands. So WMV HD content will transcode, as will MPEG-4, but unsupported video codecs like Ogg Theora (or MPEG-2) won't.

By the way, the limitations are primarily driven by the power of the CPU and digital signal processor on the device. Above some combination of pixels, framerate, and bitrate, the hardware can't keep up and starts dropping frames, which makes video playback jerky. Also, higher quality video hits the battery harder and drops battery life.

Hey, will the Zune allow multiple artists and/or genres? I like how in Windows Media Player 11, these things work beautifully, and I was wondering if it'd work the same on the Zune

Yes, it'll work exactly the same as in Windows Media Player 11, multiple artists and genres and all.

I'll take transcoding if it's done seamlessly. Sounds good enough for me.

Is there any chance for the zune to be able to handle any lossless Audio format in the future on it's current hardware?
