Sorry it took so long to reply. Sound is a bit buggy at the moment. That's the next thing I really need to work on. It doesn't really lag, but it doesn't sound too great either. To me, it seems to sound better on low-bitrate streams that I've downloaded from the internet (archive.org has a ton of cool old movies that have fallen into the public domain) but on VCD, it's not so great. I have a few ideas, so I should be able to improve it at some point. I've found most stuff watchable, and the audio and video don't drift out of sync, so you may want to give it a try with a few short movies and see what you think about the sound quality.
