[snip] Abimelech, whose name is Semitic, was king of the Philistines. His captain, Phicol, had a non-Semitic name. [/snip]

[snip] Since we do not yet possess sufficient epigraphic material of a Philistine language (with the exceptions perhaps of the Deir Alla tablets and the seal at Ashdod, both still undeciphered), this etymology for Achish may be premature. The commentary also cites Mitchell (1967, 415), who points out that the name Achish was found on an Eighteenth Dynasty (Late Bronze Age) Egyptian writing board with Cretan (kftyw) names... The name Goliath, like Achish, is not Semitic, but rather Anatolian (McCarter 1980, 291, Mitchell 1967, 415; Wainwright 1959, 79). [/snip]

[snip] The most striking finds in this Deir el-Balah dig site were uncovered while excavating the cemetery, namely, anthropoid clay coffins with removable lids in the shape of heads. None of the heads pictured on these coffins, however, wore the feathered headdress of the Sea Peoples (see p. 59); their headgear was of an Egyptian style. [/snip]

[snip] 11. Albright uses the study of names and the Luwian dialect to place the origin of the Philistines in southwest Anatolia... 1. Naveh (1985, 9, 13 n. 14) states that Ikausu, the name of the king of Ekron in the seventh century b.c., is a non-Semitic name that can be associated with that of the Achish of Gath in David’s time. The name in the seventh century has a shin ending that is non-West Semitic. [/snip]
Some of these History Channel shows are so bad that I hesitate to mention it but here goes anyway.
Maybe 5 years ago they had one about ancient Israel and the Philistines. They actually called the Philistines (The Sea People) and suggested they came from Greece.
