My videos are MP4 files. In brief, I found Samsung Blu-ray players better for streaming than the the PS3.
Here is my story.
I converted to digital video in 2006 using a Mac MIni attached to my family room TV. I was satisfied at first, but the video quality wasn't as good as the DVDs I converted to MP4. When I bought a PS3 for Blu-ray play in 2007, I experimented with various streamers and used Plex for a while, the quality was much better than the Mac video player, but I wasn't crazy about Plex menus. I really didn't need a game machine and bought a Samsung BD-D6500 in 2011. I was surprised to find that the streamed video quality seemed superior to the PS3, I also found a really nice streamer (Mezzmo) that allowed my to customize the streamed video menus displayed on my player
I was happy with two exceptions. Mezzmo is Windows only which required me simultaneously run Virtual Windows on my Mac ( a pain when required to re-boot), and the Samsung would not display Netflix subtitles. ( streamed subtitles worked )
So about 6 months ago, I decided to replace the Samsung Blu-Ray. I tried a Sony which displayed video streaming fine, but Netflix video quality was noticeably inferior to the Samsung. I returned the Sony and purchased a Samsung Samsung BD-E6500. Now I had Netflix subtitles and good native MP4 streaming audio. Then I found that Netflix Super HD ( digital audio ) would cause my new Samsung to occasionally buffer unless I downgraded to PCM audio. This was certainly unacceptable especially with with 30 MB/s internet. Samsung said send it back for repair and I did. For an unknown reason they replaced the motherboard, because it came back with same problem I sent it with. I was getting a bit exasperated.
Next I tried a Roku box for Netflix and MLB. Eureka! everything works as advertised and it is flat out fast. This solved the internet streaming problem.
Now for my local files. When I found that VLC had a nice iPad remote app, I tried VLC on my Mac for local files. Lo and behold super video quality, subtitles, a good menu and the bonus of a built in audio equalizer, I don't even have to run Windows.
However, I still have an occasional video burp. I am still playing the VLC FFmpeg settings and haven't completely solved the problem. ( my current Mac is a 2.5Ghz i5 with 8 mb RAM )
