Good thing you have slim ps3 and this htib works for you. But for me having fat ps3 make me returned this htib and gladly got full refund on my money. This htib have rear speakers switching problem when having pcm input, thus, fat ps3 cant bitstream hd audio and no choice but set it to pcm. See below detail got from onkyo press release...

A firmware error has been found on some of Onkyo’s new A/V receivers and home theater systems. When playing back certain Blu-ray Disc and gaming software with 5.1- or 7.1-channel PCM audio content, the left and right channel output is reversed for the surround speakers. This occurs when the HDMI output of the source device (e.g. Blu-ray player) is set to multichannel PCM mode.
Initial production batches of the following models are affected by this issue:
TX-SR308, TX-SR508, HT-S3300, HT-S3305, HT-S5300, and HTX-22HDX.
Please note that no problems occur with a 2.1-channel configuration, or with formats other than multichannel PCM (e.g. Dolby Digital and DTS function normally).
Onkyo is providing a firmware update for each affected model. Owners are requested to contact their local Onkyo distributor.
I called ONKYO official distributor (Toyama Group Center) kasi and they didn't even know about the issue.
