DVB-S EPG not working w/ Haupauge Nova-S

[newyankee]

Thanks to sub's hard work we got diseqc working on the Hauppauge Nova SE/S-Plus cards.

However, there seems to be a problem with the DVB-S EPG updates. I have configured 3 capture sources, for some channels without a DVB EPG I use xmltv (one source), and I have 2 others using the DVB EPG.

When starting the EPG updates from the tray application, from within config or automatically, just one transponder appears to be scanned and then the update is terminated.

This seems to be be problem:

Unexpected failed in DvbEpgReader.LoadChannels(): System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
at NativeUtilities.BDARecorder.GetPsiParserEPG()
at GBPVR.Backend.Common.DvbEpgReader.LoadChannels(IEpgUpdateProgressCallback callback)

However, if I go into config and set the first channel from the transponder list using the rescan feature/preview window and the update the EPG, it works. I have to do this for each of the two DVB EPG capture sources, otherwise there's no update.

I suspect that the switching latency of the diseqc switch causes the first tuning request to fail and the EPG update starts without a locked signal and thus fails. A longer EPG harvest time setting doesn't change this behaviour.

I have attached some with non working and working examples.

I suspect GB-PVR's PSI Parser doesnt like something that is contained in the EIT part of the broadcast stream, and its balking.

Do you have access to a web server? If so, we could look at recording a transport stream so I can play it back here in the debugger.

I do have a web server. How do I record a TS with the Hauppauge card?

Would that EIT part problem explain why it does work when I tune to a channel first and then update the EPG?

I think you can use dvbstreamexplorer (google should locate it). I'd probably need at least 80MB, but ideally I'd get a minutes worth (about 250MB).

I'm not really sure. Maybe.

I am kind of stuck here. I can't get dvbstreamexplorer to work. Don't get past the first satellite config screen - it always crashes no matter what I enter there.

I tried numerours re-installs to no avail. So for now I can't record a TS.

Ok. Sorry I dont really have any other suggestions for how to record a complete TS.

[newyankee]

Got it working (once only though). I was able to record something; it will be on my web server in about 5 1/2 hrs (link in pm). I am not sure though if I recorded the TS I intended to record as the diseqc options in dvbstreamexplorer are thin.

Please take a look. It should be the 11836 H mux

Are you going to send PM containing the link?

I've spent a couple of hows look at this today with no real progress. I can see the error occuring when I use your transport stream, but I dont seem to be able to catch it in the debugger. I'll spend a bit more time look at it though before giving up.

Hi,

I think I am having an identical problem with my setup too. At least it appears that way. I haven't checked the logs to see if the same error is present. Which log file should I check?

If there is anything I can provide to help in troubleshooting let me know. I'm using a Twinhan 102G with diseqc. 2 sources on DVB EPG and 1 with zap2it.

cheers
