PVRX2 spikes CPU to 100% every 12 sec. during record.

[josim]

Short version/to the point!

During recording PVRX2 process spikes in CPU usage every 12 seconds. It will go to 90%+ which bring total CPU usage to 100%. OTA ATSC signal via HVR-950.
GB-PVR v1.2.13/ Compaq Presario 2100US laptop/2.0Ghz Celeron/ 512MB RAM(64MB of this for Video) Recording to an ext. hard drive thru a USB 2.0 PCMCIA adapter. I understand this unit is not robust enough for playback, only attempting to record.

Long version/additional background.

The laptop described above is 5.5 years old and I wanted to replace with a desktop. Rather than just putting this in storage, I thought I might be able to put it to good use in some way. Began thinking about Mythbuntu but was hesitant to make the leap to a new OS etc., as I am still using this laptop for some daily applications. Wife has a 1 year old Toshiba but usually keeps it busy. Soooo, download and installed GB-PVR, we fought a few skirmishes, and I beat it into submission.

The unit does seem to be able to record HD OTA signals. CPU usage between spikes runs 20 something %.

I have since purchase a desktop w/o monitor (HP a6528p w/E2200/3GB RAM/500GB HD/Vista Home Premium 32 bit.). It is able to record and playback using VMC( I have it connected to our 1080P TV). Recordings made on the laptop via GBPVR play on the desktop and look good between the spikes and then break-up and judder during the spikes.

Help please!:confused:

The PVXR2 process doesnt do the recordings, so I wouldnt expect it to be doing any different during a recording. Or do you mean the GBPVRRecordingService.exe process? If it is the PVRX2.exe process, then I'd expect it to be doing it regardless of whether its recording or not.

Sub, Thanks for your reply!

Yes is is the PVRx2 process that spikes for an instant. Verified this while viewing Task Manager/processes. I also notice that Task Manager process increases. I think this is in response to the increase with PVERx2.exe.


It is weird! ???

edit: The recording process stays in the 18-28% range. Tried to upload a bitmapped screenshot of the task mgr. Looks like a heart monitor w/sharp peaks and wide valleys.

Do you mean you see an extra PVRX2.exe process appear in the task manage process list?

On the "MVP&NMT" tab of the config app, do you have it set to auto start any servers?

[josim]

Autostart = 0

However, PVRX2 spikes after running for a minute or two, recording or not!
Your smart!

Yes I see PVRx2 in the Task Mgr Process list. I watched carefully and see the % jump to 90ish%.

Save the picture as a jpg, then upload it.

Please confirm there is only one instance of PVRX2.exe listed in the task manager process list?

Sub,

I'm, sorry! I'm having trouble getting the bit mapped image down to a small enough size to meet the forums requirements.

I'll keep working on it.

Sub,

I zipped it.

Daggone! You can't see that.

I'll keep working on it

Does it matter what screen you're on in PVRX2?

Do you have anything in the plugins directory?
