To follow up and "add" a bit to my last post on this -- Looking at these a little more closely, and assuming nothing on your end is stripping anything out, just going by what I can see from the "exporttoHTML" from TSreader ... looks to me like quite a bit of stuff is missing from the streams from TW vs. what is sent by the station, OTA. And that's just what I can tell from TSreader's exporttoHTML function ... Don't know about the EIA-708(digital captions) captions or STT, or other PSIP tables(MGT, RRT/etc) and whether they're in there via TW or not(they are there OTA) ....
For example, via TW+your Tsreader html output files compared to mine OTA -- Via TW there are no detailed program descriptions in the EIT's, they're there OTA. Service Name for KET4 and CET world seem to be missing via TW, There OTA. Oddly enough, Service Name for "Tube" OTA is "WXIX" via TW's Mux. EIT's seem to be missing completely from WCET-DT via TW. As noted earlier, lots of stuff(Info on the elementary audio/video streams mostly) is not showing up from the TVCT via TW(that goes for all program streams from WLWT-DT, WCVN-DT(KET), WXIX-DT and WCET-DT.
Most importantly, perhaps -- In your 19:07 cap, The audio/video streams from KET3 appear to be missing as well(They are not present in PID usage chart, nor are they shown in stream descriptors/etc. in PMT, for instance), as if the stream is "not" there, which, while should be the case between 8pm~12am, should not be the case when they are in SD mode(which should be the case at 19:07EDT). Looking at that, it looks like you aren't getting the streams from KET3 even when you should be, can't imagine how you could decode them.
What I also find odd is the PID address of 0x0052 for KET3 (program5) via TW's mux. The PID's for any program stream I've ever seen OTA has been 0x00[x]0 PID for the program, 0x00[x]1 for the video, 0x00[x]4 for one audio stream, and if present, 0x00[x]5 for the alternate audio stream. I wonder if that has anything to do with the Audio/video streams for KET3 not showing up in the 19:07 cap.
To be "comlete"+to allow you to compare these to your caps as well, I've attched a zip file to this message from around noon today with HTML output from TSreader for WLWT-DT, WCET-DT and WXIX-DT streams. Probably never reallylooked at it/paid attnetion to it before, but I don't recall the PID's being at 0x0050/51/54 and 0x0060/61/64 for the program streams, most station's have PID address of 0x0030 for their "first" program.
Do keep in mind that CET does not send "Create" OTA, just CET-HD and World, so we don't get that third stream from them that's in the mux on 85 you're getting OTA. Also, notice that the PID's/streams for WLWT's EIT's are present at time of this capture, they just are either not being implemented/recognized properly, or perhaps more likely, there is no info in them, currently.
Also, it might be helpful to explain how this works with my equipment/setup/etc. TSreader is reading the TS "directly" in real time rather than from a TSfile captured and dumped to to disk, earlier. When you're not reading a TS file as source in TSreader(which seems to be the case in your case judging from your HTML output files), and are using a input source that works with TSreader which allows you to "interfaces" directly to your "tuner" card drivers+Directshow BDA source filter -- a box in TSreader pops up when you open it that lets you tune the desired channel/frequency - such as channeel 24 for WCVN-DT, 35 for WLWT-DT/etc. If, however I use other applications to capture+dump the TS file to disk first, then read the TS file in TSreader like you are doing, everything shown in TSreader is, however exactly the same as using the ATSC BDA source filter in "real time", it's just not happening in real time.
The reason I bring that up is because something entirely different happens if I capture from Firewire port of my Sony KD34XBR960 HDTV with capDVHS or VLC or other capture software --- The sony only sends the program stream for the station it's internal ATSC(or QAM) receiver is "tuned" to, and strips everything else out ... In other words, the streams aren't decoded, but are demuxed before making it to the firewire port, and the only streams you get via firewire are the video/audio streams for the particular subchannel the sony is "tuned to", no PSIP/etc ... I wouldn't think that would be the case with any PC tuner cards(especially since most of them, like mine don't even have MPEG2 hardware decoders and don't demux or mux streams in hardware), but I don't know, so thought I should mention it ....
That's probably about all I'll have on this -- probably not, but hopefully there's something useful in there somewhere to someone regarding my posts on this ...
