Problem switching from analog channel to another analog channel

[superman2012]

Hi.

I'm having problem with NPVR 2.2.6 with latest patches.

Windows 7 x64
Hauppauge HVR1300 for analog channels only.
Hauppauge HVR1200 for digital channels only.

Live TV
I can switch from analog to digital.
I can switch from digital to analog.
I can switch from digital to digital.

But I cannot switch from analog channel to another another channel. When I select another analog channel, the live preview screen will freeze and nothing happens. (npvr didn't hang)
I have to go to a digital channel before I go to another analog channel.

For example :
I cannot switch from analog channel A to analog channel B.
I have to switch to any digital channel from analog channel A before I can go to analog B.

May I know what is the problem?
Thank you.

Does changing the audio decoders make any difference?

Either way, reproduce the problem then zip and attach box npvr.log and nrecord.log and I'll take a look.

changing audio decoders doesn't help.

here is a new set of log.
thanks for your help.

Unfortunately I cant see an obvious cause in those logs.

My build is no longer compatible with 2.2.6 so I'm not currently in a position to provide patches, but if this problem still happens in the next release, I'll help you work through it. (and I'm about to jump on a plane in a few hours, so not able to commit any time right now)

It's ok. I can use gbpvr at the moment.
Thanks again for your help.

With one tuner shouldn't this jump to "now 2"

notice also that NextPVR tries to renew the second lease it got, after requesting the channel change:

2011-12-01 08:02:17.778 [DEBUG][1] Client got streaming handle: 190003
.......
2011-12-01 08:02:27.808 [DEBUG][1] Client about to request renewal of handle: 190003

and NRecord claims to renew it ok:

2011-12-01 08:02:27.809 [DEBUG][16] Renew lease ok (0x190003)

but this is all 10 seconds AFTER NRecord has already torn down the graph at 08:02:17.768!

Hi.
I have 2 x HVR1300 and 2 x HVR1200 but have disabled the first HVR1300 and first HVR1200 for other uses.
Leaving only the second HVR1300 and HVR1200 for NPVR usage.

Sorry, I don't understand all these.

@superman2012 - I was more talking to martin and sub than you. Basically Martin and I are pointing out that after you change channels once, NRecord thinks it's still providing a live tv stream to NextPVR (as evidenced by the log entries pertaining to streaming handles), yet at the same time has already shut down the tuner because it thinks nothing is using it. In other words, the left hand has lost track of what the right hand is doing.

It's an npvr bug, nothing you can do about the problem until sub releases the next version. If you're lucky sub will see the error in the code based on the logs posted and this problem will already be fixed in the next version; otherwise you'll have to reproduce the same problem with the next version, post the logs, and wait for sub to produce a patch.

In the meantime, your best bet is to always change channels by exiting LiveTV back to the TV Guide (escape key); this causes NextPVR to fully shut down LiveTV, and then when you select a new program to watch it will restart LiveTV properly regardless of what type of channel you were last on.
