I just downloaded the latest Tester episode straight on my Vita, and the file is 2206MB despite being 960x540. The 720p version on PS3 is usually around 1200-1300MB, and are higher resolution than the Vita version. Since most SD trailers downloaded on the PS3 can't be copied over to Vita via Content Manager, the Vita needs specific videos. Why are they so much larger, yet the resolution is not as sharp?
I found that weird... I just didn't bother downloading it on my Vita and downloaded the HD version on my PS3.
Maybe they forgot to compress it?
Anyways, I don't think that should happen. If the SD version is like that on PS3 (I haven't checked), it should be that particular video's problem. I've downloaded previous episodes on my PS3 in SD and transferred them, and they were no bigger than 800 MB.
