Interesting Video/Network/Xine issue.[Sorted]

Hi all,

Last evening I was down in the Man Cave intending to watch a show I had recorded. So I go to the video menu, select the recording, and start to play back. And what do I see, slow, sluggish video performance. So I figure that the network is just moshed up from running a week w/out a reboot. So I reboot the core/hybrid, wait and then all the MD's come back up again.

So I go to watch my video again, same issue. Well as I did not want another reboot, I fired up MythTV and watchied it from the recordings menu. And it played flawlessly. So no I am curious. So I drop out of that, try again from the video menu, same slow performance.

Out of curiosity, I fire up a DVD that I had ripped and it plays flawlessly. So I grab another TV show recording, Torchwood, from the video menu, slow dragging performance. Fire up MythTV, recordings menu, same show, perfect playback.

So here is the question. Is there something about MythTV recordings that xine is not happy with?

Do I need to change the format I record in, currently I record in MythTV at 720x480, .vs the default 480x480 for SD.

But then why does MythTV work so well, but the default video player not, at least for recordings?

This was the same on all my MD's.
Hardware spec outs.

Man Cave - P4 3.GHz w/ 2G ram, ATI radeon variant running UI1 Gigabit connection
Master Bedroom - AMD64 3400+ 2G ram, Nvidia 6100 on-board card UI2-Masked 10/100 connection
Playroom - P4 1.7GHz w/512MB ram, Intel onboard UI1 10/100 connection

However, the core/hybrid plays these videos flawlessly from the video menu or MythTV.

Core/Hybrid - AMD 64 x2  2.2GHz dual core 2G ram Nvidia 7300GS Gigabit to the Gigabit house switch (irrelevant I know, but it is feeding a Gig network switch)

Any ideas. Things I should look at. Personal experiences that are similar?

Regards,

Seth

It seems, at least in testing that I have resolved the issue. I changed the way mythtv recordings were captured, to try to get a more "realistic" picture from a post I read here in the forums. And the post works well, at the local TV, in this case my core/hybrid. The initial settings were to make all SD recordings 480x480 when captured.

I changed this to 720x480. Per the forum post. I am thinking because of the size of the file, or perhaps the format it was captured in was causing the issue. Here are some screen shots to show the differences in the recordings:

The first image is the recordings with the modifications, the ones that would not playback well on an MD.

The second image is after the changes were reset to default, and these play swimmingly.

So at least in my case, leaving the defaults was the solution. My picture is still outstanding, very watchable, so for now I will leave the settings as default.
