The slow loading of the series, movies, sports events, and live tv sections are problem created by your IPTV provider. Sometimes they include something like 70000 items (between series, movies on demand, sports events/PPV and live channels) and I have seen up to a 100000 items. This is a huge amount of data packed into a single blast file and on top of that, this single m3u file contains many formatting discrepancies. The bigger the offering from the IPTV provider, the greater the chance of a slow initial loading. However, I can assure you that SFVIP Player handles really well even the heaviest lists. It is a great and very optimized program, so I don't see what else can be improved in that direction. Just be patient, or switch to a different IPTV provider.
