Very good Blu-ray player, but

I own the Sony BDP-S490 now since a few days and am very satisfied
He plays Blu-rays without any problems from (I to 50 BDs) run all
In true MKV files I surprised he even plays MKVs from the positive refused my LG Blu-ray player. The player is also really good to use the menus are clear and the remote fits comfortably in your hand.
Unfortunately, now comes the but, the player plays a lot Avi Files not on ca 30 tested I would say not ran good half unfortunately, but happens my LG BD Player with no problem
What also stands out very positively the upscaler brings out a lot of DVDs out there and make a very good picture
Also, the player plays the formats: MP4 and WMV from (I'm here not very many but where I've tested there were no problems)
Conclusion: Anyone looking for a very good BD and DVD player and MKV files will play makes this machine nothing wrong, unfortunately, as I said, the problem with Avi Files
