Hello. I got my Asus Transformer two days ago, and so far I'm very pleased with it. I have one problem however. When I try to watch some of my MKV movies in 720 or 1080p, it is very laggy and there's no sound. I have tried with the standard movie player and several other ones found on the market. After searching the internet, I found that Honeycomb doesn't support the MKV format, so to be able to play movies, I have to convert them to mp4. The converted movies play fine on my transformer, but after trying many different programs for converting, I found that the fastest program takes 3 or 4 hours to convert a single movie, and I just don't have the patience for that. What do you guys do when watching movies on your tablets? Thanks.
