[mythtv-users] Frontend for HD Content question.

[Nick Ellson]

Ok, I have tried recording and playback with no setting changes.

When I go to Watch TV, Select my first HDHR Tuner and press record and 
watch it a second I still see the issues with jitter. I navigate away to 
the main memu and wait 10 mins. I come back to Watch Recorded TV and 
select the program that is currently recording. It starts off where I 
first started recording but the playback is MUCH better. Only tiny 
glitches when teh news was showing a football play and there was massive 
color changes. It stayed like that while i watched. When I stopped 
recording and started playback again, it was the same as the second time.. 
Very good playback except for a glitch here and there and it was 
consistant glitches so i suspect they got commited to disk as the 
recording process was running.

Now, last night when it was just nasty, my wife also had two other NTSC 
recordings from the PVR500 spooling to disk. So perhaps Disk IO is an 
issue. I may need to dedicate a drive for the HD Content... Can I separate 
the storage locations per tuner?

I also want to look at the idea of dedicating a NIC on the back end just 
for the HDHome Run, that sounded like a nice idea. And see how the profile 
change works as well.

Thanks for all the ideas everyone!

  Nick
