1: I'm [still] missing a few tapes
I have found most of the previously-lost tapes, but a few haven't [yet] been found
2: I miss a few tapes
I often think longingly of a few tapes that I no longer have
I'm pretty sure that #1 can carry sense #2 in "Indian English", but that's certainly not true of "mainstream" English.
Unless still or some equivalent is included, nothing about #1 carries any implications as to whether the "missing" tapes will ever be found / replaced. But even if still is present, that simply implies the speaker is continuing to try and locate the outstanding items (a goal he may never actually achieve).
Note - missing is an ergative verb here, in that a few tapes in #1 is the object of the verb, but we can recast to make that the subject, with the same meaning (except in this particular case, rephrasing loses the original subject completely)...
