After converting HD *.tivo files (from a series 4, if that matters) into *.mpg with DirectShowDump, I am tearing my hair out trying to edit them. Interestingly, my Tivo Desktop (non-plus) can't play the downloaded *.tivo files, but once I run them through DirectShowDump, media player can play them just fine--and they're in sync, no problems. But when I open them in an editor, they have nasty sync assymetries, and running them through PVAstrumento doesn't help (the result is unwatchable because of stutters). After spending a while searching for solutions, I came across this "known issue" from the kmttg "known issues" page (I haven't tried kmttg, so I lack prior familiarity with its documentation): "Encoding creates audio/video sync issues--Recordings originating from Tivos very often have timestamp defects that lead to problems if not corrected before encoding to other video formats. VideoRedo Quick Stream Fix is the only (non-free) tool out there that can reliably correct these defects such that when you encode the faulty recording to other formats it will be perfectly in sync." As a result of all this, I have two questions: 1. It doesn't make sense to me that the DirectShowDump *.mpg's play back just fine but once I open them in an editor (whether Mpg2Cut2, CutAssistant with VirtualDub, or Avidemux--same result in all three), there are sync problems; and that PVAstrumento identifies sync problems so bad that it can't adequately fix them. Why in unholy cyberHades are the files synced in players but not in an editors? 2. I thought maybe that if I coughed up the dough for Desktop Plus, which activates those hoidy-toidy MainConcept codecs, the sync problems would be solved. But if the kmttg site is correct, using Plus won't make any difference; only VideoRedo will do the trick. So is the kmttg assertion accurate? There's really nothing out there, including Desktop Plus, that will resolve this issue? It sticks in my craw to pay $50 for only a single feature in VDR to deal with something that is Tivo's fault and which they themselves should have fixed long ago. (One user, in post 8157811, says that kmttg+handbrake, set up a certain way, will encode to mp4 without sync problems, but he doesn't say whether he edits or not; if he doesn't edit, then I suspect that he's in the same boat as me, with converted files that play back fine in players but have sync problems in editors.) Thanks for any ideas.
