beggar can't be chooser.
Up to you if you want to wait until someone decided to upload an mkv version,
or to download these while the links are still available.

I tried to reencode them but for some reason there's this blocky artifact that keep showing up in my encodes. :/

Get mkvtoolnix and remux it yourself.

if you simply talk about mkv and ogm in general, there's no different. And as mentioned in the comment above, you can use MKVToolNIX to put it in an MKV container without re-encoding it and it's fast.
What matters is the encoding.

if possible ,yes please

Thanks! i need this. By the way i try to download this https://btdb.to/torrent/ymVmxZWgXrTmO9...iq7rW.html but it's in spanish subs while the external english subs are waful (google translated i guess). Is this similar to this or is it different subs?

sir betamax can you reupload the link for the batch?

sir, can you reupload the alternative version, namely H.264/AC3? Thanks!

Sir BetaMAX can you reupload this alternate version (H.264/AC3)? the dead link removed. much appreciate it thanks!
