Poor Manthorp. The malicious pixies of frustratingly-close-but-not-close-enough have made the program work perfectly but fixed the output resolution at 224x176 whereas his player will only accept 96x64. The program was designed to offer a range, but it looks like it's been messed with and the option is greyed out.
