With the growing popularity of DIY PVR units the Theater 550Pro unit based off of ATI's Theater 550 chip may be the ideal solution, especially for those that are just retiring older hardware as upgrades roll along. Other key features include a 3DComb filter and hardware noise reduction which should help filter out garbage in poor cable signals.
