Your British IPTV plays FLAC but not APE or WavPack. Your IPTV reseller's British IPTV panel supports only the most common lossless format, and their IPTV panel ignores others. The pattern that keeps showing up across British IPTV lossless variety complaints is this: an IPTV reseller using a cheap IPTV reseller panel has limited lossless support. A British IPTV reseller with a professional IPTV panel supports APE, WavPack, FLAC, ALAC, and more. A real-world example: a user's British IPTV played FLAC but not his APE collection. His IPTV reseller said "FLAC is standard." That said, ask your British IPTV seller: "What lossless formats does your IPTV panel support?" A comprehensive IPTV reseller will list multiple formats. Quick practical breakdown: a complete IPTV panel supports all major lossless codecs. Test with various lossless formats during trial. In most cases, the British IPTV reseller whose lossless library plays fully has broad support; the one with gaps doesn't. Honestly, having British IPTV ignore half my lossless music collection was frustrating. The IPTV reseller's IPTV panel was format-snobbish.
