Memory leak? Out of memory exception error

[BigMoose]

I decided to give nPVR a go for the evening viewing with the wife instead of GBPVR, with the Wave skin - which is really nice! So it's the first time I've had it running for over 2 hours, but it threw an "out of memory" exception - although the channel was still showing in the background. I had a look in the task manager and the npvr.exe process was running at 570Mb which I thought was rather high. I copied the exception log text but not sure it's any use...

I've had a few similar errors but was going to wait a day or so until my win7 install settled down a bit before reporting them.
I can "sort of" cause them to happen by channel surfing, going through the EPG, watching a channel for a second or two, ESCaping back to the guide and moving to the next channel. After about 15 to 20 channel swaps, the exception pops up with "out of memory".
I'll get the exception info later hopefully, when the shack is down to a habitable temperature.

In a normal evening in front of the telly I'd channel hop enough. It's not my win7 install as running gbpvr I don't ever get such issues and don't reboot it for weeks. I was using the +/- for channel hopping, not going via the guide but I was pressing up to view what's on for the current channel and using this to browse the guide info for other channels...

I wasn't implying it was related to Win7 - just that I've only had it on a short time and didn't want to report a problem like that until I was sure Win7 was stable in itself.
My old XP gbpvr machine gets rebooted about every three weeks to wake up the nova-t-500 or its driver when it tends to nod off.

Me too has the "out of memory error" problem on Windows 7... but with GB-PVR. I think it has to do with my disabling of the pagefile. On all Vista machines i got never an error message like this.

I run GBPVR and NPVR on the same box (win7 x64) and haven't done anything to the pagefile. GBPVR never does this but NPVR does - although I've tried to get it to do it again this evening and failed. While watching the football it seemed to stay around 140Mb for the pvr process. When I tried flicking round lots of channels it did go up but not dramatically and certainly not much over 200. However when I was messing about with the config, after several times of starting/stopping live TV and going in and out of the settings menu I noticed it had settled around 470Mb while on live TV. So I restarted it and was back to 140Mb.

Hmm, something isn't right when its been running for a while. I get choppy audio for any mpeg1 channel after watching for a while (like over an hour). Not sure about AC3 channels. I've tried different decoders but doesn't make a difference. Using the same as I do on GBPVR and npvr and it happens on npvr but I can watch for ours on gbpvr.

I've been away for the last three days, and just happen to have left live tv running over that time. I just checked that machine, and it seems to be running fine with a reasonably low memory usage (90MB). This was a SD channel with MPEG2 video and MPEG1 Layer II audio.

Is it specific activities that is causing the memory to jump up?

The one thing I've noticed today that caused it was coming in and out of live tv and tinkering within the settings menu. Then when I had another look in task manager it was up to 470Mb. I'll keep playing around to see if anything else seems to cause it. Annoyingly (or not!) when the sound went crappy, the mem usage was still low enough (150Mb). Obviously not the application though if it's fine for you after 3 days. It's odd that it behaves differently to GBPVR on my box though both memory and the audio thing.

If you're back, if you have the time at some point are you able to take a look at npvr's choice of audio stream when there's >1? To see if it can pick the AC3 channel and not the mpeg1 Narrative one?

Its probably not what you're seeing, but I know updating the EPG in the Settings menu can consume a lot of memory if you've got a large number of channels. NPVR effectively frees this memory after its no longer in use, but because of the way .net memory manage management works it wont free that memory back to the operating system until the operating system tells the .net runtim that it's running low and needs to reclaim unused memory. (ie, its assuming that if you needed that much memory at some stage, then you'll probably need it again in the future)

For your sound issue, have you tried other audio decoders?

I am back. I cant remember, does it do this when you playback a recording, or only when you watch live tv?
