In OS version 8.0.84, players accept a force_igmp_version registry entry in the networking section. This entry allows for customization of the player response to the IGMP network environment. It can have the following values:
- 0: The default behavior. The player will use IGMPv3 unless a querier with an older version is present, in which case the player will fall back to v2 or v1.
- 1: The player will always use IGMPv1.
- 2 : The player will use IGMPv2 if possible, but will fall back to v1 if an older querier is present.
- 3 : The player will only use IGMPv3 and will not fall back to v1 or v2.
