For the longest time, at least since Mythbuntu 8.10, on some occasions some HD programs will stutter when played back. I have tired all the playback profiles, but none seemed to smooth out the stuttering. Also, it was not consistent what episodes of a given show would stutter. Transcoding the file only occasionally fixed the problem and sometimes messed up the A/V sync.<br>
<br>During an 'ah-ha' moment, I realized that on the episodes that stuttered, the recording would start before the channel was tuned in. FWIW, the tuner is a SA3250 cable box controlled by firewire. What I then tried was, while the program is playing, open the menu and edit the program, putting a cut point after the progam I want to watch starts and deleting eveything before the cut point. Then when I exit out of the editor, the stuttering stops!<br>
<br>I can only guess why this works, but I think that if I knew how to delay the recording until the channel has been changed, I would not have to worry about why and stop having to do this quick edit. Until then, I hope this works for some of you who also suffer with this issue.<br>
