I've upgraded usually just one or the other and I can tell you that from my experience at least, the freezing was introduced with the ivtv drivers that made a big change in the DMA code. I know if I drop back to 0.3.2h right now, it will work just fine, because it did only a few days ago before I got the newest verisons to load properly with my setup (but, I'll lose the nice functionality of my pvr150...sound gets messed up sometimes with 0.3.2h ... it's a lose-lose situation at this point). So, while it's easy to blame ivtv, I'm not going to be quick and jump to this conclusion for the reasons I stated in my previous email. I still think there's something going on with the MythTV code as well. This reminds me, actually, of two other problems I have with playback, which I don't think are ivtv related: 1) Although I haven't played with this much to give a perfect description, I'll try from what I remember: While in Live TV, when rewinding in 3x, after resuming playback, the video will rewind at super speeds and go to a point far from where you intended to playback. I'm not sure if this is after FFWing a bit or what, but it definitely does not do what I'm expecting it to do 2) When FFWing in 3x mode, the timestamp does not also speed up to 3x. It just counts in 1 second intervals as if it was playing back normally from the first place. This could very well be the cause of problem #1, where the time positions are off so when rewinding at 3x, it's catching up to the real position it should have been at (note that when rewinding at 3x the timestamp moves at the correct, 3x rate). Anyway, just something to consider. At this point I'm not sure who's the culprit. I may dive into the ivtv playback code in myth if I can find some time and see if I can spot anything unusual. I wish there was some documentation to help me out, but at least the code is extremely clean (browsed through it last night), so I might have a chance :-) ~Lou
