The PAL speedup isn't really a big deal for the silent Chaplins, true, but it hurts the sound films, i.e. LIMELIGHT. And the smearing due to the shoddy conversions is absolutely inexcusable.
Michael must be smokin' that stuff again. ;) They are lousy. PAL-speedup, shoddy PAL-to-NTSC conversions which result in slight strobing artifacts (more noticeable on some titles than others), and shortened versions of many of the original films. The aspect ratios are often compromised as well...
