If someone can send me a good guide on providing patches correctly that would be a great help. Meanwhile the issue is if you're performing a dvbv5-scan or dvbv5-tune it produces errors if you use the LNB type L10750 as the upper frequency range is too low. Common LNBs used for SkyTV NZ and similar services in Australia have an upper range of 12750. Example - https://www.dishtv.co.nz/LNB107KU Here is a patch against the current git tree.
