| Post subject: | pause during fast forward or rewind |
I have sticky fast forward enabled. When I fastforward or rewind It will go for ~5 secs and then pauses. If I hit fast forward again it will continue. It happens in sd or hi def. Any Suggestions Rkshack |

What happens if you disable sticky keys? |

Looks like this is a known bug. Was originally reported for the PVR-350 but now reports from people (including myself) indicate that it is happening on other PVR-x50 hardware. Google for "MythTv ff rew freeze" and you will quickly find that we are not alone. At present it looks like the workaround is going to be disabling sticky keys and tweaking the skip ahead/behind times. I hope a fix is found for this quickly but I not really having any difficulty navigating with the sticky keys disabled. Martian |

I'm not sure if this is the same problem, as I didn't have sticky keys enabled, but I had a similar problem of the screen freezing (not the frontend) when fast forwarding or rewinding mpeg2 video (specifically SD recordings from a pvr500). The problem did not occur with video transcoded to mpeg4. The fix I found was to change the mpeg2 decoder in settings->playback from libmpeg2 to "standard" which I believe uses ffmpeg. On my rigs with P4-3GHz only doing SD I couldn't tell the difference, but I believe Human wrote that the best HD results were with libmpeg2 as the decoder, so you may have to weigh the advantages. |

Changing to standard from libmpeg2 fixed me right up too. This may present a probem for me as have heard libmpeg2 is better performance for HD conent moving forward. |

| Post subject: | frozen screen during rewind / skip back during live TV |
I am having a similar problem, freezing during rewind (Skip back). But the proposed solutions are not working for me. I have sticky keys disabled, and I have my mpeg2 recorder settings are STANDARD, which are supposed to eliminate this problem. Is there anything else I can try or check? I have a PVR-150. When I used the WinTV Go cards (software encoding), I never had this problem. I switched to the PVR-150 to offload some CPU/HD Paul |

Sounds like me too. But I'm using HDTV right now. I'll try switching to Standard from libmpeg2 and see if it fixes things as well. |

FWIW - The FF and REW have always been iffy in MyrthTV. You're usually better off skipping with the arrows... IMO it's actually faster too. |

Can you adjust the time that the arrows "skip"? I'm 99% sure each arrow (it's actually the >>| key on the streamzap remote) goes in 1 minute increments, which always overshoots by about 15-20 seconds (or I "undershoot" and have to FF another 15-20 seconds). Too bad that it can't handle the FF/RW better, but I'll try the diff. mpeg and see what happens. It was actually fine when I was at VGA. When I kicked it over to DVI (720p output) is when things got ugly. |

Yes. I believe it's under Playback (Recording?) groups in MythTV 0.20 the defaults are 30 forward and 5 back. The asymetry is intentional. I often use, <number> <right-arrow> to skip most of the block then another <right arrow> or so then a <left arrow> or two. This all happens about as fast as I can think it. and within a second or two I'm in the right place. |

Solved my FF/RW problem. Apparently I did change the mpeg encoding. Switched back to "standard" (as was suggested) and the problem goes away. Yay! |
