The Bottom Line
Although not offering the extensive connectivity, features, and more complex audio/video processing of higher-end units, the TX-SR304 offers essentials for today's entry-level user: Excellent sound quality, HD-compatible component video switching for use with HDTVs, and an easy-to-use remote control. However, adding some front panel AV inputs and a dedicated turntable input would have added to its value. I give the Onkyo TX-SR304 a rating of 4.5 of 5 Stars.

Guide Review - Onkyo TX-SR304 5.1 Channel Entry-Level Home Theater Receiver - Review
I found that the TX-SR304 had no problem passing HD signals though the component video connections up to 1080i (I did not test any 1080p signals) through to both a Syntax LT-32HV LCD TV and an Optoma H56 DLP video projector. The TX-SR304 offers adequate composite video connection performance. It must be noted that this receiver does not have S-video inputs or outputs.
As far as audio performance goes, I was very surprised at how well the Onkyo TX-SR304 sounded. I used the TX-SR304 with a Klipsch Quintet III 5-channel speaker system, in conjunction with a Klipsch Sub10 Powered Subwoofer. The TX-SR304 delivered clean, non-fatiguing sound, even at higher listening levels: Both analog and digital audio input options delivered very good results.
Although the TX-SR304 does not offer the multitude of surround sound and DSP options of more expensive home theater receivers, what audio processing options it does offer are practical and deliver where it counts: Sound Quality.
Also, despite its modest rated power output (65 WPC) the Onkyo performs well in both in average small and medium-sized room, making it an excellent option for apartment and second room home theater systems.
While not having all the bells and whistles of home theater receivers in higher price ranges, the TX-SR304 offers practical, basic, features and solid audio/video performance.
