I have recorded all my vynil records onto my PC using Wavepad and had no probs with this, I have tried to transfer some of them onto my digital photo frame, some will i.e. MP3s but the others .wav will not play on my photo frame how can I convert the .wav files to MP3

I use mp3workshop to convert or resample my ripped vinyl. Available free from MP3 Workshop Homepage

Thanks colbtech I'll try that

There is a nice application you can use for conversion, download here
