Sony S350 or PS3 80GB

[PCFan]

I recently bought a Sony S350 Blu-ray player but I returned it because it would not resume where I left off if I ejected the DVD. Also I was testing out Three's Company: Season 6 Disc 3 on it and it would give me combing artifacts and stuttering unless I change the video conversion mode to Video in the setup menu of the player. I tried a Sony Upconverting DVD player and I could leave the video conversion mode on Auto and that DVD would play just fine. Also Windows Media Player and Windows Media Center in Vista would give me the same combing artifacts on that disc and I don't know if there is a way to fix it in WMP or WMC. No combing artifacts on that disc on my brother's PS3. I haven't tried a USB flash drive on the S350. Would a USB flash drive allow multidisc resume DVD on the S350. A multidisc resume feature is important to me because I watch seasons of different TV shows and like to alternate discs of different TV shows depending on what I'm in the mood for without losing where I last left off on the discs. Should I get a PS3 instead of the Sony S350?
