User theparasol added many enhancements to DVBapi with version 8680 (05.06.2013). One of interesting enhancements is new PMT mode.

If you are using OpenPLi 3.0 then I suggest you select mode PMT 6 (you can find this option in OScam WebIf under Configuration/DVB-Api) and you can expect faster zapping! I tested this feature on my Vu+ Duo and you can really notice the difference. This mode is not available on other images, only on OpenPLi and OpenPLi derivates!

Do not forget to select option ReopenOnZap. If you not, then you will get black screen after a few zaps. You do not want that 😉
