Messed up Recording--NAS

[DATAstrm]

I have set up a NAS box using Naslite and raid5 for all of my files. This includes my recordings.

Lately I've noticed that some recordings are messed up. To be specific, the recordings often skip forward, freeze up, or display blocks.

Last night I copied a few hundred gigs to my NAS, and in the morning, the recordings that were scheduled during the copy time were only 250megabytes, instead of their usual 3GB.

I'm assuming that the bandwidth was all taken up by my copy process and gbpvr was not able to record properly? Is there any way or plans to implement a way to detect when a recording fails in this way? IE the write operation fails? Specifically how is recoridng the stream handled?

Another problem I'm having is watching a show while its recording. IE Chase play. I can watch finished recordings fine on multiple computers with no skipping. I can also record fine while watching another show. However if i try to watch a show while its recording, i get horrible skipping~around 2-5fps.

Watching the recording after its done in wmp or gbpvr is fine, but watching during the recording process from the NAS doesnt' work.

Any ideas?

No. In most situations the data is written to disk by third party directshow components, and I have no visibility of whether those disk writes succeed or fail. Also, its been this way in GB-PVR forever and hasnt caused many problems in the past, so its not something I'm too concerned about.

The disk activity required for watching in progress recordings is pretty demanding. It sounds like you NAS is not able to keep up. (I'm assuming it works fine for you from your local hard drive, and the problem only occurs when using the NAS)

I do intend to do some improvements around the effeciency of this activity in the near future (to help PC client performance), but I cant tell you when that will be ready.
