no live tv

[lexip]

Hi installed NPVR yesterday and having a weird problem.

I'm using a generic usb digital tv dongle which works fine with microsofts media centre, mediaportal & totalmedia.

When using NPVR it does everything - epg, recording etc.

Recorded programs record all the way to the end and play back fine.

But it won't display live TV.

I've checked the temp folder where the live TV is stored and it creates the file, but stops after approx 6000kb.

The 6000kb file will play.

It's like it starts to store a buffer for playback but when it gets to the point of actually playing the live TV it aborts the live recording.

Anyone got any ideas?

Reproduce the problem, then post the npvr.log and nrecord.log and I'll take a look.

Hi

Tried to reinstall and had lots of problems - ended up with it unable to start device - anyway got that fixed an I am now back to the original problem with no live TV.

Logs are too big.

I think the problem is here:-

Zip and attach the logs and I'll take a look.

OK, here they are.

It looks like you havnt gone to the Settings -> Decoders screen and selected the decoders you want to use.

[lexip]

Yes I have.

I initially forgot to do this when I reinstalled, and surely I wouldn't be able to play back the recorded programs if no decoders had been selected.

Could it be a problem with the decoders I have selected?

What decoders do you recommend I use?

[lexip]

Being doing a little more testing.

Don't know if this helps work out whats wrong, but I can watch a program whilst it is recording, but it doesn't work when I try live TV (just a black screen and no sound) - in fact the program ends up not responding and I have to close it down with task manager.

I've also found that after this happens I can't get either mediaportal of windows media centre to work - I get a message up for an "unknown error".

The only way to recover from this point is to reboot - closing down all programs and processes, unplugging the usb dongle doesn't work.

Can't help but think the error "Live stream expired without renewal." is where the problem lies.

In the attempted live session in those logs, it looks like it is unable to find the selected decoders, so it ends up with a graph with no video decoder (and not MPEG1 Layer II audio decoder):

What decoders do you recommend I use?

There is a lot of people using a lot of different decoders. What decoders options do you have available on your machine?

[Reddwarf]

I'd recommend the Cyberlink decoders, if I'm not wrong it is contained in CCCP (Combined Community Codec Pack)
