Recording Service / webservice causing recording errors

[ThaHandy]

Hi,

I've the feeling this has to do due to I'm using a network tuner "Silicondust HDHomeRun HDHR3-4DC Tuner"

adding that extra load on the OS (kernel time). Because when I'm using the PCI tuner there are mostly no errors.

This issue mostly occur when the recording service is busy in the background, ie. starting/stopping a

record or me using the Recording Service webGUI.

Setting the priority to high seems to help a bit, but the issue remains.

Any ideas?

This is not very serious imho. I'm recording from cable daily and I have errors in almost every recording..

These can just be simple AC3 frame errors or little discrepancies in the signal. I hardly see them when I view the recording later..

..there are no AC3 frames, and yes, it is serious!

[ThaHandy]

The errors I have are real errors. The video is glitching for a split second if i check on those times.

Recordings can be flawless as long i don't touch the service.(i have 100% signal) Below is a recording of 12 hours!

To bad the recording service and the web service are one deal. otherwise I'd kicked the webserver to idle.

So, any info how rs is dealing with the data? Where the lag can be? Any debug info?

[Piers]

I've noticed recording errors when using the RS to record, using another application there are no issues with streams.

 

However, it's still a very impressive application and worth the money.
