5. NPS is a little slower than H2 because it's Java and my desktop PC is CPU-bound using an old 400MHz P3. H2 is I/O-bound because it's usually going through a 100Mbit network to the media server or the HTPC.
6. The "long pause problem" definitely occurs on stripped-only streams. I'm not sure what happens with edited-only streams. I usually do both. I may try TSreader again, but I only have the limited demo version. It's probably worth the money to buy it if I can successfully strip down all of Alias Season 4. I'm missing one or two ep's so I'm pissed they're not re-running them. What's up with that???
7. I've gotten the frozen picture once or twice, but if I backed up the edit point on the cut-in another I-frame or two, it would clear itself up. The scrambled picture I would get only if I didn't follow the rules stated above. It may still be happening, but who's going to see a blocky breakup if the screen is all faded to black?
I'm using 1.10.3 with the preview display off.
8. I started using 2000MB file size in MyHD. This made it easier to edit (combining files) and then stripping a single edited file. NPS does not have automatic next file processing when using the MyHD file naming convention. It may work with HiPix naming convention - not sure. I use 9000MB file size now in MyHD, so it probably doesn't matter for hour-long programs - and may decrease processing time for sub-channel stripped streams since the files are smaller before they get to H2.
