Is anyone getting perfectly smooth playback of HD-PVR files with the HD100

[Chriscic]

Yes! Thanks Sic0048!

Ok, I shouldn't be so happy, but now I know it's not just me.

Question is now, does everyone have this and just aren't noticing because it's small? Can you really watch the CNN HD ticker for 1 full minute with silky smooth text scrolling and no micro glitches?

Sic0048, yes if you rewind they will happen in different places.

There are other times I sense a micro glitch when just watching regular (e.g. no scrolling text) HD channels, so it's not a trivial issue to me.

Everything needs to work really smoothly (audio sync, upcoming 5.1, silky smooth playback) before I bite the bullet with 1-2 more HD-DVRs and 3 more Sage HD extenders.

I'm watching CNN as I type this. There is no stutter at all on the crawl.

I can, however, understand your concern. Prior to purchasing my HDPVR I had downloaded a sample HRPVR generated Sportscenter file from the Geektonic website. It had a noticeable micro stutter every 5 seconds or so on the crawl. That was the first thing I looked for after I completed the HDPVR install.

I think the main issue is, it's a crap shoot. I my case I was lucky. I guess you could RMA it if you lose the bet.

The problem is I'm not sure where the crap-shoot lies. Is it with the HD-PVR itself, or with the HD100?

Doesn't seem like it should be the HD-PVR, since the glitches happen in different places if you rewind, unless there's some subtle issue with the recorded files; that seems unlikely.

You're not the only one. I have the same types of stutters... very subtle but noticeable. Only with shows recorded on the HDPVR.

[Chriscic]

I'm waiting (as are many) on pins and needles waiting for the new HD-PVR drivers/firmware to see if that solves the problems.

So so so close to an awesome whole-house solution... but still so far...

Take a look at this thread from a ways back. http://forums.sagetv.com/forums/show...9&postcount=13

I have this issue, and because of it, I ran with much older code on my HD100s for smooth playback of the HD-PVR, but over the weekend I updated to the latest as I was having issues with my HD-HR, the micro stutter from the HD-PVR is way better than the lock ups I was getting on the HD-HR... oh well.

From Narflex himself "A detailed stream anlysis of the HD-PVR's H.264 encoding does show that there are errors in some of the buffering indicators which hardware decoders rely on to properly playback the streams."

I have not tried switching from 720p to 1080i to see if this gets better, mostly because I'm lazy, but also because I'm stubborn and I don't really care about 1080i when all my TVs are 720p... I suppose I should just try it for now

[Chriscic]

I'm already running at 1080i across the board, from STB output to HD100 output to the TVs (although doubt the latter matters). Need... new... drivers

[jrog]

switched it to 1080i, and indeed, the stutters are gone. CNN ticker is smooth, but I do notice more Audio delay issues than with 720p. Pick your poison, I suppose.

Are you using an integrated network card on the pc? Seen that cause problems. If you've got access to a pci card give that a try.

It's an add-in card. Anyway, since I've tried three different server machines with exactly the same result, I know it's not my network card. Thanks for the suggestion though.

[jrog]

After many months of back and forth with Narflex and others with much more insight than I, it basically comes down to the drivers for the HD-PVR needing to fix some issues. I was mostly happy with old code where the playback was smooth, but other functions that had been improved, like my HD-HR, forced me to update and live with the H.264 issues until Hauppauge comes out with a fix.

My network is a bit messy, with 2 switches between 2 of my extenders and 1 in between the third, but I only have the problem as a result of different software/firmware/driver configurations.

[Chriscic]

Agreed. Probably not much more to discuss on this topic until new drivers arrive someday.

Buy a R5000-HD

No stutter on CNN crawler and no audio sync problem. Another case of; "you get what you pay for".

[Chriscic]

I may well end up doing that. But not yet. Have to give the new drivers a chance first whenever that is.
