Thanks so much to Bunkus for writing this incredibly useful utility. I had a bunch of H.264 .mp4 movies sitting on my hard drive that were unplayable on my JVC XV-bp1 blu-ray player. JVC just updated the bp1's firmware to fully support MKV playback. Now, thanks to MKVToolnix, I can watch movies from my USB flash drive --> bp1 in full, upscaled 1080p glory! Wonderful!!!
