So why not use a pid:type there, like for pmt_extra? A problem i see for the pmt_extra is that it can never represent a full PMT entry (for example: CA descriptors). But i don't think we should want this, as i can't image something useful. However, just using the PMT-type won't work. AC3 channels have the same type as Videotext ("private" iirc.), and for DTS you have a descriptor with an ascii ID. We still need some per-service "flags", for example to disable PAT/PMT parsing (to rely only on the pmt_extra stuff). Felix
