I have a Desktop [Ubuntu 10.4] streaming to my PS3 via MediaTomb currently. Works very well.

I want to add DVR to the mix so I can record my shows but watch them through MediaTomb on the PS3. I have no intention of hooking my PC to the TV directly.

Whats the best way to go about this? I've been reading about MythTV but I I've never set one up. Is MythTV the answer or is there a better option.

I still have to buy hardware to do this, I'm on a budget.

Thankyou for your time,
Drezliok
