Both tracks are in WMP library, but when asked to 'Burn To Disc' the burn is refused because there is insufficient capacity on the disc.
What is the running time of the wav(s) you're trying to burn?..
Remember Audio CD is ~74-79 min of audio..Might need to split the wav..
If I used OGG when prompted, would this allow the two tracks (both sides of a 60min audio tape) to fit onto the 700mb disc??
Only if you burn a DATA disc, or ~700mb of data..If you choose to burn a standard(see wiki link)Audio CD, from the OGG files, the burning app will convert/decode to wav 16/44.1khz/ 1,411 kbps..When burning a standard Audio CD from the wav(s), it is the running time that matters..Again, 74~79 min of audio, max..
