I play league at 1600x900 and playstv just wont record it. Does it have to be a 16:9 resolution for playstv to record the game?
It should record at any resolution, although you might get black bars since the support is only for 16:9. But you're saying that it's not recording at all?
It wasn't at first, but now it does. The only thing now is that the recording looks like static but with some of the game still visible
That typically happens due to some interference; usually with drivers.
I'm not sure what type of PC you have, but I'd recommend updating your video drivers.
Any further assistance, and I'd probably need to get client logs to investigate. Here is how to send them: LINK
