System requirements for older versions

I'm looking for a list of system requirements for older versions of Serviio, I'm running 10.7.5 on a mac which can't upgrade it's OS any further. I have Serviio 1.4.1.2 running on this machine and increasingly I get issues playing file types, MKV in particular (I've tried changing the profiles in the console app). I'm hoping there's a more recent version with improvements for this. It's a Sony Bravia TV.

Advice appreciated,

Thanks.

Any thoughts?

Nothing?

Since 1.5 Serviio requires 64bit Macs, so you will be stuck on that version I'm affraid.
