I don't have the answer to your question, but I have been using a CFW PS3 as a media center for about a year now and would like to share.
The PS3, without any modifications, can play most video files off a USB or external drive. I use a 3TB external drive loaded with movies, cartoons, and anime that are 4:3. Right off the bat, the two biggest problems were overscan, which the PS3 natively suffers from, and the fact that .mkv files are not supported. Another issue was the lack of support for subs, which meant needing hard-embedded subs that would usually get cut off due to overscan.
The solution to these problems came with the homebrew program Movian. Movian lets you adjust the scale of the video, which lets you get around the atrocious overscan. It also has support for subs, but it isn't as versatile as any other PC media center app, so I still use hard subs.
Movian also supports .mkv files, with the big caveat that there may be slowdown due to the way the file was encoded. I'm not gonna pretend I know a lot about video files and video encoding, but basically, if the file was encoded in 10-bit, it's not gonna play at the correct speed and will stutter like hell. Another big problem with Movian is the lack of DVD and Blu-ray support. You can't pop in an official release of something and play the video using Movian, so you're still stuck with that horrible overscan on DVDs. As a side note, Blu-rays on PS3 will also play incorrectly, as they suffer from extreme underscan.
I'm sure there are other means of setting up a CRT media center with more versatility and support, but I still like the PS3 due to PSX and PS2 support with a wireless controller. And the fact that I'm retarded and struggle with most computer stuff.
TL;DR Movian saves PS3 as a media center, but you're gonna want hard subs on anime, you're gonna need to make sure every file is encoded in not 10-bit, and to avoid all of this is you're using DVDs or Blu-ray. I just use PS2 for DVDs instead.
