I'm having trouble replacing a PGC with vobblanker. When I go to replace it, the final size is larger than the original, but I've checked the file sizes of the replacing PGC and it's less than half the original. Further, when I attempt to process, vobblanker halts with a cell not found error. There were no errors muxing. The celltimes.txt was created by pgcdemux and I removed the last line to avoid an error with muxman.
