Hi Joseph. A bit of a coincidence, the files I am playing with are also Battlestar Galactica. Specifically S2 E10 & E15.
Both of these I had mastered to HD DVD without any problems using Mpeg2VCR to convert the entire .TS to .MPG for MF5. But when I viewed them, that was when I noted several video freezes / pauses during playback (all other eps were OK).
I have now re-converted both eps, by:
1. Confirming via Mpeg2Repair (log only) that there were indeed long timestamp gaps in original .TS files for these eps.
2. Running the original .TS through VideoRedo "Quickstream fix" with .TS output.
3. Re-confirming via Mpeg2Repair (log only) that there were now no timestamp gaps in the new .TS files.
4. Converting the .TS to .MPG for MF5, via Mpeg2VCR.
5. Confirmed that both new HD DVD discs now play flawlessly, with no freeze / pauses, and no lipsync issues etc.
a. For both eps, if I converted to .MPG via VideoRedo, the resulting .MPG files would freeze MF5 when trying to open the files (when converted via Mpeg2VCR, they imported into MF5 immediately). Note: I had never personally experienced this problem before, as I normally use Mpeg2VCR for the .MPG conversion.
b. With both eps, if I tried to step back through Mpeg2VCR timeline to try and manually edit out the timestamp gaps, Mpeg2VCR would stop responding at the point where I wanted to mark an end edit point (based on your and Roberts comments, I assume this is not however a problem with all "timestamp gap" source files).
c. Although unrelated, it is worth mentioning that before importing the resulting .MPG into MF5, I also passed these eps through DVDPatcher to convert the frames from 1280x1088 to 1280x1080. MF5 therefore did no re-encoding!
Although I understand that you might certainly be able to manually identify and edit out each timestamp gap using Mpeg2VCR (with some .TS streams), this did not work for me on these particular .TS files. I would also comment that using the "Quickstream fix" tool, is a very straightforward and seemingly effective solution for this timestamp gap issue (although it involves another $50 piece of shareware - but I don't mind paying for useful software).
I am now making a practice of passing all .TS streams (that I intend to convert to HD DVD), through the logging only option of Mpeg2Repair (ie. no repair). This is also useful for confirming average bitrate, and the overall condition of the .TS file.
If Mpeg2Repair identifies any timestamp gaps, I then pass the .TS file through the "Quickstream fix" tool (to a .TS output file), before using Mpeg2VCR for .TS to .MPG conversion (and any other editing I wish to do).
