R5000 recording woes

I still don't understand this. You seemed to indicate that Cyberlink PowerDVD played back the stored recording just fine. If that's true, then everything from the R5000-HD to the disk worked as it should. If you had problems with anything playing back the stored program fine, then you should look at the server.

This sounds like a client playback issue.

Turak,

I have the same problem as you. It seems if more than 1 HD show is recording (or playing live) at the same time - I get very stuttered recordings. Did you say that problem went away with the NEC chipset?

I am not talking client playback issues - been round and round with them too - this is a USB contention issue. I was planning on seperating the 4 feeds to two different servers to decrease the load.

What were your results with the NEC chipset specifically - and can you post the link to the exact care you purchased? Have you tried recording 3 HD shows at once?

Thanks!

Exactly. If he can playback mpeg2 HD, he had no recording problems and since h.264 has a lower bit-rate than mpeg2 (in general), it should be fine too. This is definitively a playback issue, unless the network throughput is not big enough since playback is not done in the server.

Having said that, using a good quality USB card is a good move. I noticed lower CPU utilization when I started using the NEC USB/PCI card, in addition to solving all my recording corruption problems. I also get much faster file transfers when I move my video to an USB drive.

Well, I'm not Turak but I got this one from newegg: http://www.newegg.com/Product/Produc...82E16815124008

Note that I didn't had stuttering problems. It was much worse, getting corrupted recordings every now and then. For $10 it's worth a try, and you also get the benefit of faster file transfers, etc. I have recorded two HD shows at once while transferring some files to an USB drive.
